After searching through 1000's of pennies - found this one gem... Ill post my sorted results later but thought I would share this - it is nearly identical to the same size as a US penny:

Wait, what? Thats a tid bit of info that I never knew before? @NatedoggAZ welcome to Coin Talk! I have found a few myself. Mostly from the '70's as well. Thanks for sharing!
