Nice! :-) But a silly question - how do you differentiate between bronze and copper? weight? colour? David Not a silly question at all, and I guess the only 100% test would be a metallurgical analysis. Bronze is around 95% -97% copper, so the relative densities are almost identical, hence weight doesn't really help. I bought my coin from Mark Rasmussen who owned, and has handled, many other similar proofs. He assured me that the coloration of this coin, compared to the otherwise identical bronze proofs, was very evident. The same difference that exists between the 'yellow/brown olive' toned examples of pre 1860 copper pennies and the subsequent bronze coinage which doesn't exhibit the same toning. In hand it is very evident. Thanks! Circulated copper and bronze certainly have a different "feel" in hand, copper being softer. I've several jetons where I'm just not sure
