Ok for the bronze coins I can take them back and refund. I asked them to silver plate the bullet and they came fully plated. The difference in material is obvious from the plating defects on the bronze ones. I probably should have mentioned it before posting out but I was quite behind on some orders so I just tried to get them out. My fault really. So returns are accepted on these no problem at all.
That's me taking a gamble too as I might not get back the winning coin.
The thing is, I don't want a refund. I want a coin that at least looks or feels different than the silver one. Right now I have two different coins, with different prices, that look, feel and weigh exactly the same.
