Hello all. I've been digging through the attic again and have come across a beautiful 1787 George III sixpence in extremely fine condition, possibly uncirculated. It's bright on the reverse with a patina on the obverse. However, it has been made into a badge, with a simple pin/hook fixing soldered to the obverse in two areas. It seems I'm going to be one of those coin collectors who go for superficial appearance rather than intrinsic value, I am severely tempted to get a jeweller to remove the fixing as it's a beautiful coin, but I'm guessing this would be a bad thing to do? Assuming that the clasp was put on around the time of circulation, I reckon if I did get the solder removed it would leave two pale spots in the patina, which would not be desirable. This seemed like a good time to at least ask what the thinking is on coins that are mounted as jewellery. Do the same rules follow as for cleaning, ie Don't do it?
