Description: Anyway it was full of fun, including this piece. So I'm going to call this a 60/40 piece. By weight its probably more like 90/10! Many collectors and dealers take these and dissolve all the calcite off in acid so all you have left at the end is the copper.
Winning Bid: USD $28 - 10 bids (Year Sold: 2021 )
