Premium quality Bi-Plate Infinity 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. Great way to honor an Alcoholics Anonymous member who has passed away with this fine eternity chip
