Why are high grade autographed baseballs and baseball cards worth what they are today? Because so many were defaced by passionate kids with a pen.
Today, kids update their MySpace or Facebook pages. Back in the 1950s and 60s, they wrote on their sports cards. Their name. Their opinion of the player. Maybe some personal airbrushing. Those who pull those cards out of storage think of what might have been had they resisted the urge.
The same holds true for other sports memorabilia. It wasn’t worth anything back then. Nothing tangible, really. But times have changed and those kids who grew up in baseball’s golden age have the evidence to prove their artistic and creative abilities were alive and well.
At least one, though, told the Wall Street Journal he doesn’t regret his ‘improvements’ to the 1968 Topps Mickey Mantle.
