Nice! The ONLY think I like about the shield cents is the clashes. I have yet to find one in circulation.
If you were born with a silver spoon in your mouth The 72 doubled dies would be easy to find without even trying. You could just dig out a little pocket change and buy your self a truck load.
I live in Denver... not many Philly coins around here. Denver almost never screws up on coins, so it’s rather boring looking through pocket change.
