i would never had noticed that it was a fake. besides the detached bill, what else gave it away? Lighter color? Lighter weight? Different type of coinage?
A few ago i had found a 2000W two dollar coin in change. It caught my eyes right away because in 2000, they only circulated the knowledge 2000 $2. The regular polar bear $2 2000, and 2000W were only issued in proof. Could mine be a fake?
