what causes this type of indent in a penny? is it a dieclash? i have other dieclashes i found where memorial is very present on front of coin, and on back it looks like this. this one just has it on the back. is it lincolns head that dies struck together and formed a die clash?
confirm? looks to me like a reverse die clash from research. looks to be on the light side. pics dont show it as well as looking at the coin. anyhow confirm?deny?
