1960 Roosevelt Dime Doubled Die - Counterfeit

Ah yes, no sky puppies in Antarctica just visiting. My wife's job had taken her to the other six, so we went down so she could finish her seven continents and see lots and lots of penguins, whales and scenery.

I've always wondered about doubling on cast coins. I once read that the process of making counterfeits increases the chances of a doubled die, which seems to be true given how many of my counterfeits have doubling, but exactly how that works remains a mystery to me.

Because they can. Practice for a more nefarious endeavour.
