What condition my condition is in: The Chicago Sun-Times takes a look at Comics Guaranty LLC, the industry's arbiter of all things mint and near-mint:

"Out of the nearly 500,000 comic books graded by CGC since its founding in 2000, only 641, or about one-tenth of 1 percent, have merited a perfect 10, a rating known as 'gem mint.' But rating alone does not determine a comic book's market value. Rarity factors in. For example, while a Spider-Man Number 53 given a 9.8 might fetch a few thousand dollars, a Spider-Man No. 1 in the same condition would go for about $200,000, Haspel said."
