Even if you pass all these tests, your card’s value depends on condition. A First Edition with a crease is like a prize-winning pig with a limp—still valuable, but less impressive.
Professional grading companies (PSA, BGS) will assess your card and slap it in a plastic tomb. A Gem Mint 10 First Edition Charizard can sell for $300,000 or more. Yes, that’s a down payment on a house, for a piece of cardboard with a fire lizard.
So, before you toss that shoebox in the trash, take a breath. Check for the shadow, the stamp, and the font. You might be holding a treasure, or you might be holding a reminder of simpler times. Either way, don’t use it as a coaster. Please.
