Silver Age Key Issues
The Silver Age (roughly 1956 to 1970) reintroduced superheroes and produced many of the hobby's most valuable first appearances. Low surviving populations in high grade make graded census scarcity the dominant value driver for genuine Silver Age keys.
Silver Age keys are where superhero collecting was reborn. This hub collects the cataloged Silver Age keys with first-appearance context and explains why a single grade point can move the price sharply on scarce, decades-old books.

Silver Age Key Issues: FAQ
Why are Silver Age keys so valuable?+
Two reasons: they include the first appearances of many enduring characters, and very few copies survived in high grade. That scarcity means graded high-grade Silver Age keys can sell for many multiples of a mid-grade copy of the same issue.
