Premium quality Bi-Plate 46 Year AA Sobriety Medallion in Elegant Black and Gold Silver Plated design . Gold plating is very glossy, this coin looks like its ready for a white tie affair. Serenity Prayer on the back and designed with recessed colored lettering around the rim and raised triangle for a great look and feel. Size is 33mm x 3mm diameter. To give it a better "feel" and "weight" we made it 12 gauge vs the usual 14 gauge sobriety coins so it is 3mm thick. When you hold it in your hand you'll know the difference. Comes in a protective vinyl envelope. If you need a keychain holder search Amazon for B01GLOWDJY which is the ASIN for the holder that works with this item.
