A pierced or soldered coin loses much of its numismatic value forever. That is why we never touch the metal of the piece.
Our setting is a bespoke ring that embraces the coin's edge. It holds firmly, but can be released at any time, leaving the coin intact — it remains numismatics, not scrap jewellery.
Reversible means intact
Unaltered, the piece keeps its full historical and collector's value. You wear history without destroying it: that is the whole idea.
