The most famous coin-user is Billy Gibbons of ZZ Top. Supposedly he uses a Mexican peso. But he has also been know to stretch the truth when it comes to biographical facts, so who knows.

I would think a coin would ruin a finish right quick if one wasn't real careful.

I usually use Dunlop Tortex, most often the yello mediums, iirc they're 73 mm. Heavier for bass, I think those are blue or purple and 106 mm.
