Rick M. asks: I have a Indian Head Cent that is an error and I can’t find any information about it specifically. It has a regular die on the obverse and is smooth and has no die on the reverse.
Your one sided Indian cent is one sided because:
A – Someone planned off the reverse in a machine shop (more common than you think)
B – Something came between the coin and the die when it was struck. Most of the time, that something leaves a visible mark or impression on the blank side. If nothing is visible see A.
