Premium quality Bi-Plate 33 Year AA 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 or 1 5/16" diameter. 3mm Thick to give it a better "feel" and "weight" we made it 12 gauge vs the usual 14 gauge sobriety coins. 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.
