Hey fren, just finished to read the previous bread, busy days for my MTG business (as often before Xmas) i'm posting few pics of the bracelet rn.
Interested into mirrin' your dad mexican bracelet too if you have the chance to get a pic!

Good news, great news and bad news concerning my bracelet frens.
Just came back from a buyback gold & jeweler shop to see if the coins were legit (was already 99% sure, but wanted to be 100%). They indeed are in gold and silver. A bit sad he had to file down a bit 1 of each to be certain it wasn't plating, but i presented him the already most damaged ones so it's not that terrible.
Even greater news is he had access to a numismatic catalogue for pros online, and we couldn't find any entry for the gold (4 reales equivalent) 'commemorative' coins of Presidente General Barillas from Guatemala. He looked quite surprised to say the least, and told me the coin must be incredibly rare to not be listed there (he think of few hundreds range). I told him my internet searches wielded zero results aswell, so it seems my best chance now is to directly contact the guatemalan museum of money or whatever is their governmental body who can have this kind of archives. So potentially big monies here!

Now the bad news.. he told me what i feared : the solders are in silver, and since silver's melting point is close to the one of gold, if we separate them there will always be a layer/glut of silver on the gold coins where the solder points are. Only way to remove them would be to melt them down, but the gold would melt too. Maybe some other technique not involving heating them exist, idk. I was thinking of acids maybe? Since silver react pretty strongly to nitric acid, maybe progressively injecting acid in the interstices could eat the silver solder away and leave the gold intact? I've no idea, i'd have to dig this up, but if the coins are indeed super-giga rare, it's worth giving it a chance.
