On August 29, 2026, three eBay listing statements covering three very different parts of Black Canary's career — her team series from the 2000s, the series she co-signed with her partner at the same time, and the historic team title from the 1960s-70s where she joined the main lineup — display the same central value: $9.99 median, to the nearest cent, across ad populations of sizes neighboring areas (183, 175 and 174 uncertified lots). The high ends have nothing in common: $58.00, $124.99 and $800.00 requested at the maximum. In other words, this character does not read like a multi-level market but like a plateau: the same price level absorbs almost everything that bears his name, whatever the era. These amounts are sums claimed by sellers on a single date, not concluded transactions, and an isolated measurement says nothing about developments.
There is a lazy way of talking about the price of a character: add up their appearances, identify the oldest ones, deduce a pyramid. Black Canary resists this reading. By separately questioning three sets of advertisements which have neither the same age, nor the same editorial format, nor the same public of collectors, we obtain three distributions whose center is rigorously superimposable. This is not an approximation or a convenient rounding: the three medians fall on the same value, $9.99, a figure which is not insignificant since it corresponds to a psychological threshold that sellers deliberately choose.
This coincidence calls for an explanation, and the most honest explanation is not the most flattering for the character: Black Canary is probably one of those heroes whose market value is not concentrated anywhere. It is everywhere, but diluted. The remainder of this article details what the three surveys show, what they do not show, and why center overlap coexists with dramatic top divergence.
What exactly the three readings say
Let's take the three measurements as they are, without smoothing. On the “2000s team series” pan, 183 listings without certification range from $1.92 to $58.00, with a median of $9.99; next to it, only three certified lots, claimed between $60.00 and $80.00. On the “series co-signed with its partner” section, 175 uncertified listings range from $1.79 to $124.99, median identical to $9.99, while four certified lots ask from $50.99 to $179.99, with $74.50 for central value. On the “historic team title” side, 174 uncertified ads cover a much wider range, from $1.99 to $800.00, and yet the median remains exactly $9.99; the certified segment is much more extensive, fourteen lots asked from $77.95 to $514.20, median at $244.62. Each of these amounts is a price displayed on August 29, 2026 by a seller who hopes to obtain it, never an amount collected.
One identical center, three completely different shapes
The identity of the medians would be a weak fact if it described three similar populations. It is striking precisely because these populations are not at all. We must therefore carefully separate two properties of a distribution: where its midpoint is located, and how it stretches around this point.
The midpoint does not move
Three researches, three decades of publication, three editorial formats, and a single central value. From similar numbers - 174, 175 and 183 advertisements - half of the sellers ask for less than ten dollars and the other half more, in each of the three cases. The common floor therefore relates to something common to the three sections, not to their specific content.
The peaks diverge by a factor of fourteen
$58.00 for the first set, $124.99 for the second, $800.00 for the third: the maximum claimed varies in a ratio of more than thirteen between the extremes. This upward dispersion is the truly differentiating information. It survives the flattening of the medians intact, which proves that the three sets are not interchangeable.
Certification follows the same hierarchy
Three lots certified on one side, four in the middle, fourteen for the historic title, with central values which climb from $74.50 to $244.62 depending on the sets where they can be calculated. Where the recent section motivates almost no one to have a copy authenticated, the older section attracts several times more. This asymmetry is consistent with the divergence of the maxima.
A high tail is not a prize
The maximum of $800.00 is one ad, only one, published by a person who freely sets the amount. There is no indication that a buyer has validated it or even considered it. A single peak measures a seller's ambition; the median summarizes the position of a hundred and a half sellers at a time, and this is why it is more resistant to noise.
The conclusion to be drawn from this is more subtle than a simple “everything is equal”. This character's market does have a structure: the old section houses objects for which certain sellers dare to pay unparalleled amounts elsewhere, and it attracts proportionally many more examples that have passed through certification. But this structure lives in the tail of the cast, not in its body. The body is flat, uniform, and strictly identical from one era to another. In other words: rarity exists for Black Canary, but it is in such a minority that it does not distort the general level.
An identical median over three readings is not a law of the market: it is a dated observation. It was made on August 29, 2026, at a given time, on the announcements then visible. A single measurement cannot establish any trend — neither rise, nor decline, nor lasting stability. To speak of movement, there would need to be at least two surveys spaced over time and conducted according to the same protocol.
We must add a clear methodological limitation: the three studies do not divide into watertight groups. The same lot can appear in two of them, an approximate ad title can place an object in a category that is not its own, and a seller who stacks several titles in a single lot blurs the membership. The three populations partially overlap, and this overlap is itself a candidate explanation for the convergence of the centers.
Six hypotheses to explain the plateau
The following is a matter of interpretation, not measurement. None of these leads is demonstrated by the three surveys; they are proposed because they are compatible with them and because they would be tested, in principle, by subsequent surveys.
An essentially collective career
Strongest hypothesis: Black Canary spends most of its publishing time in training, duos and shared series. When a character almost never occupies the cover alone, buyers' attention is divided among several names, and no title becomes the focal point that a market needs to designate to build a higher price floor.
Eight decades of continuous production
A character published without any real interruption since the origins of the genre continuously feeds the offer. Each decade adds its stock, and this stock does not disappear. Faced with demand that is not growing at the same rate, the mechanical abundance of supply pushes the mass of advertisements towards the bottom of the ladder, where they clump together.
The psychological threshold of ten dollars
The $9.99 value is not a statistical coincidence but a commercial reflex. This is the amount chosen by a seller who does not know what to ask and who wants to stay below the symbolic bar of ten dollars. If the three sides converge on this figure, it is perhaps less because they are equal than because they trigger the same hesitation among those who put them up for sale.
A common fund of sellers
The same professionals and semi-professionals sell entire catalogs with a uniform price list. When a significant portion of the three groups' ads come from this type of player, the median reflects their pricing policy rather than an object-by-object evaluation. This path would explain both the identity of the centers and the persistence of atypical peaks, which come from individual sellers.
Notoriety without material support
The character is widely known, including outside of comics, but this notoriety is not crystallized on any identifiable object that buyers could spontaneously name. Diffuse recognition produces diffuse interest: many curious people ready to spend little, very few determined buyers ready to pay a premium for a specific piece.
The porosity of the research itself
Methodological hypothesis that it would be dishonest to dismiss: if the three queries partially bring back the same batches, then their convergence is partly a measurement artifact. The good test would be to duplicate the ads before recalculating the medians; until this work is done, the superposition of the centers must be read with this reservation.
Why the median is the right tool here, and the maximum the wrong one
An ad report is not a sales report, and this distinction changes everything that can be learned from it. An ad registers a unilateral intention: a seller sets an amount that cannot be validated. The price displayed can remain for months without meeting anyone. As no mechanism forces a seller to be realistic, the upper part of an ad distribution accumulates the most optimistic hopes, without the slightest filter.
The median is robust to this fault: adding a crazy announcement to a population of one hundred and seventy-five hardly moves it. The maximum is entirely determined by this single announcement. This is why the comparison of maximums, in our case, must be read as a comparison of the maximum ambitions that sellers dare to formulate according to the sets - real information on the perception of the market, but not information on the prices charged.
The certified segment deserves the same caution, with a nuance in its favor. A verified copy has been subjected to an external evaluation, which reduces the uncertainty about its condition and makes the amounts a little more comparable to each other. But fourteen announcements, and a fortiori three or four, constitute numbers so low that a median calculated on them remains very unstable: one or two more announcements would significantly move it. The values of $74.50 and $244.62 must therefore be treated as orders of magnitude, not as precise benchmarks. The general estimation approach is detailed in thecharacter value guide.
What the board changes for a collector
A flat market is not a bad market; it’s a market that plays out differently. When prices rise sharply, most of the work consists of identifying the few objects that carry the value and acquiring them in the best possible condition. When they are flat, this strategy loses its interest: there is no peak to aim for, and the marginal expense to move upmarket is almost never rewarded.
The practical consequence is that the creation of a coherent whole becomes more interesting than the hunt for a unique piece. On a board, completeness costs surprisingly little compared to what it would cost for a character whose career has marked plateaus. It becomes realistic to aim for complete periods, which makes it possible to organize astructured reading pathrather than opportunistic accumulation.
That said, the opposite reading is just as defensible: the high tail of the historical pan shows that a small fraction of the corpus escapes the plateau. The collector who is looking for an object likely to stand out should therefore concentrate his attention where sellers dare the highest amounts and where certification is most frequent - without forgetting that these two signals describe supply, not demand, and that they do not guarantee any transaction.
How to redo this reading properly
An exercise of this type is only as good as the discipline of its protocol. First point: freeze the date and write it down. An ad statement is a snapshot, and an undated snapshot is unusable six months later. Second point: systematically separate certified batches from ordinary batches before any calculation, because mixing them produces a median which does not describe any real population.
Third point: record the number, the minimum, the maximum and the median, never the median alone. As our case shows, two sets can share a center and differ radically in their amplitude; note that the center amounts to erasing the most discriminating information. Fourth point: document the search terms used, since they define the whole measured. A broad query and a strict query do not measure the same thing and cannot be compared.
Finally, fifth point: repeat. The value of such a reading appears at the second measurement, when comparison becomes possible. A tracking log kept ina collection management toolmakes this repetition practicable, because it preserves the context of each observation instead of keeping only an above-ground amount.
What to note
The three identical medians are the central fact, but they are not enough to describe the market.$9.99 on all three sets, noted on August 29, 2026: this convergence is the starting point for any analysis of the character. It indicates that the same price level dominates the recent team series, the co-signed series and the historic team title. But reducing the market to this figure would be an error, since it only describes the center of three distributions whose shapes have nothing in common.
The divergence of the maxima is as important as the identity of the centers.From $58.00 to $800.00, the gap between the claimed peaks reveals that the historical section contains objects for which certain sellers express ambitions without equivalent in the other two sets. This information completely disappears if we only use the median, and this is exactly why we must always take several statistics and not just one.
Certification is three to five times more common on the older side.Fourteen verified ads versus four and three: the relationship is clear, even if the absolute numbers remain tiny. He suggests that the authentication effort is preferentially focused on ancient periods, which is intuitive, but he prohibits drawing a reliable numerical conclusion from it — fourteen observations do not form a stable statistic, and the central values of $74.50 and $244.62 must be treated as indicative.
None of these measures say anything about evolution.Everything comes from a single day of observation. To assert that the character rises, falls or stagnates would be to invent a movement where there is only one point. A second campaign conducted according to the same protocol, a few months later, would transform these figures into a series and finally make the vocabulary of the trend legitimate.
The proposed causes remain hypotheses, including the most attractive.The idea of an essentially collective career which would prevent the concentration of demand is consistent with the observations, but it does not follow from them. It must be treated as a conjecture to be tested, in the same way as the psychological threshold of ten dollars, the abundance linked to eight decades of publication or the porosity of three pieces of research. This last point deserves particular vigilance: the three sets partially overlap, and this overlap alone could produce part of the observed convergence. The publication context detailed inthe panorama of significant periodshelps formulate these hypotheses more precisely.
Impossible to decide with a single statement. The coincidence is striking, but $9.99 is also an amount that sellers choose as a commercial reflex, which greatly increases the likelihood that it will appear as the central value in any population of cheap listings. Added to this is the fact that the three researches are not watertight and probably share batches. The convergence is therefore real as an observation, but its interpretation remains open.
Because it is an isolated ad, that is to say an amount that a person has decided to register without any buyer having accepted it. Nothing in an advertisement statement distinguishes a seriously calibrated sum from a fanciful sum. A summit provides information on the highest ambition expressed in a set, not on what an object actually yields.
In the three groups noted, the amounts requested for certified lots are significantly above the median for ordinary lots. But these segments have three, four and fourteen ads: that's very few. Furthermore, certification is a choice of the seller, generally reserved for examples that he already judges to be superior, which is enough to create the gap observed without it being possible to attribute it to the certification itself.
No, and the number of announcements shows it: more than five hundred uncertified lots spread over the three searches, which implies a sustained flow of offers. A plateau describes an absence of price hierarchy, not an absence of interest. The most plausible hypothesis is that attention is spread across a very large number of issues from eight decades of publication, without ever concentrating enough to create a higher level.
There is nothing to support this, and nothing to support the opposite either. The statement describes the status of announcements as of August 29, 2026, a single point in time. The only way to know if the plateau holds is to repeat the measurement later with the same queries, the same separation between certified and ordinary batches, and the same set of statistics recorded.
