Don't see many draped busts of him. It's a nice bronze. A reverse you don't see too often. Can't help on value, maybe $60-$100.

RIC 908 Cohen 804 It is rare, but very worn and possibly polished or coated (may just be the photos). I would say about $100 in that condition. I would be interested if its for sale.
