There is a strange line, protrusion, under the letter "E" in "America" but I just don't know how to classify this. At first i thought it was a planchet error involving a gas bubble but it doesn't seem rounded enough at the edges. Any thoughts?
Agreed - in 50 years, most will look like this, no matter how you try to protect them - the OP's example is already showing signs - collecting zincolns will be a long term / future futility
