Hi Folks, I have a medallion/coin commemorating the Royal wedding of Prince Charles and Lady Diana Spencer in 1981. It may seem that this is just an ordinary coin you come accross everyday specially on ebay and such.. But the challenging part is that this coin is actually gold plated and the back has a different motif than all others i have seen so far. I do struggle to get info on this one. Can anyone help me on this? Here are the pictures of the medallion/coin. Tay
