What are your comics
really worth?
From a reading copy to a CGC 9.8 key, comic value swings on grade, key issues and census scarcity. Assay blends recent sold comps with population data into one fair value with a confidence range.
How to value comics
Comic value is led by grade — a CGC 9.8 can be worth multiples of a 9.6, and low census populations at high grade command sharp premiums.
Next come key issues (first appearances, origins, deaths), age (Golden/Silver/Bronze keys hold value best), and recent sold prices rather than asking prices.
Assay weights completed sales most heavily and reads census scarcity, returning a fair value with a confidence band for your exact issue and grade.
Grade & census
High grades with low populations carry the biggest premiums.
Key issues
First appearances, origins and deaths anchor demand.
Age & era
Golden and Silver Age keys hold value most reliably.
Sold, not asked
Completed CGC sales anchor the number, not list prices.
