Looks like Jack Bauer tortured that coin with a power buffer... Here's one I spotted on ebay--what a shiny "BU" IHC
I think it's one of those very rare weakly struck war production proof coins. The large P on the reverse stands for Proof. Probably would grade a PCGS 70
Because we are on topic, why does polishing coins munch up the value? Do you destroy a piece of it, like the thin top layer, etc.?
