Featured in Sterling Silver, this is the "old school" coin. It can be made as a pendant (left) or as the coin (right). It's solid sterling silver. In the open area, we engrave either your number of years clean (ex: XX for twenty years clean) or the actual year (ex: '94 to show that you got clean in 1994). Please specify what you want engraved and whether you want it as a pendant or coin. Allow 3 to 4 weeks for this item to be shipped.
