Mystique's first appearance: Ms. Marvel #16 (1978)

A character whose first appearance is in a series where he will not remain produces a rare market configuration: the key exists, it is old, and it took decades to be recognized.

It is this gap between publication and recognition which structures the entire file.

Ms. Marvel #16 (1978)

The character appears in a series that is not hers, facing a heroine of whom she will never be the main opponent.

Nothing in this issue announces what she will become. She serves as a passing antagonist — the most disposable role there is.

This corpus emphasizes this point, because it explains everything else:this issue was not released as a major first appearance, and no one treated it as such for a very long time.

Why a poorly located key is poorly stored

This is the central mechanism of the file, and it has direct consequences on what you will find upon purchase.

An issue identified as important upon its publication is protected: buyers put it aside, store it carefully, sometimes buy a second copy.

A number whose importance no one suspects is treated like any other: read, lent, stacked, put away in a box.

This number belongs to the second category, and has for years. When the character became popular - much later, and through other series -, copies in very good condition had already become rare.

The practical consequence is clear:the high grade bonus is justified here, contrary to what has always been the case for the famous keys. This is not a supposed scarcity but a scarcity produced by indifference.

The host series matters as much as the character

Second point, and it concerns supply rather than state.

This issue belongs to a series which was never among the best-selling of its time. Its draw is therefore lower to that of the X-Men titles of the same period.

This produces a situation that this corpus rarely encounters: a popular character key housed in a title with low circulation.

Two effects then combine. The available supply is structurally lower, and the copies in circulation come from a smaller readership, therefore less likely to have stockpiled.

This is why this file behaves better than the notoriety of the character would suggest - and this is the opposite of what we observe on keys housed in very high circulation titles.

Points of vigilance

Don't search by the character's name. Many old announcements present this issue as a simple issue of the series, without mention of the first appearance. Look for the series and number.

Check for usage defects. On a 1978 issue that has been read, examine the edge creases, spine discoloration, and staple condition—three defects that cap the grade and don't show up in a face-on photo.

Watch out for “newsstand” copies. The distribution circuits of the late 1970s produced different average states; these examples often suffered more.

Be wary of ads without a back photo. During this period, the back concentrates most of the visible defects.

As always, condition and gradation determine value; relying on real recent sales is strongly recommended.

What this first appearance teaches

A rule applicable well beyond this character.

When a key is in a series foreign to the character — because he started there before finding his place elsewhere — three things happen systematically.

It was recognized late and therefore poorly preserved. It often belongs to a title that is less widely distributed, and therefore less abundant. And it remains difficult to find by search, since the advertisements do not name it.

The three play in the same direction, and this corpus recommends treating this configuration as a signal:a poorly located key is almost always rarer in high grade than its rating suggests.
