I have recently started to collect this series of medals but I am somewhat confused. Some of the ones I have are a beautiful Bronze color, but others that I have cleaned having recieved them looking almost black are very coppery. Looking through past auctions I see that they are often described as being made of Bronze and sometimes Copper. so which is it ??? Are they always bronze but me cleaning has made them look like Copper or are there Copper versions made. Any helpful comments . Rob
