Comic Book Grade Value
A precise tool.
What is the Comic Book Grade Value & How does it work?
Comic book grading provides a standardized way to assess a book’s physical condition, which directly influences its market value.
The CGC (Certified Guaranty Company) scale ranges from 0.5 (Poor) to 10.0 (Gem Mint), and each grade is associated with a multiplier that reflects rarity and desirability.
By applying the grade multiplier to a base market price and adjusting for current market trends, collectors can estimate a realistic resale value.
V = B times G times M
V = estimated value, B = base price (USD), G = CGC grade multiplier, M = market trend multiplier
