I think it's where the copper plate was pressed during the strike, then the the exposed zinc corroded.

It's right in that spot where all those rings develop as dies wear out- maybe that's what caused the zinc to be exposed.

sorry - if this was mine i would pass it along because the zinc is a little crusty
