What have I gotss in my pocketses?

It is always possible that there's a coin in your pocket worth millions of dollars.

 (Not very likely, but at least possible.)

'It's like finding a Picasso at a garage sale': 'Fake' coin from California Gold Rush is actually REAL and worth MILLIONS and its owner had no idea

"The San Francisco Mint produced fewer than 300 special edition $5 coins, and it was thought that only three survived.

The anonymous owner of the discovered fourth coin believed the piece to be fake, as did multiple coin dealers."

So make sure you check all your loose change. You never know...
