The US Mint will release a limited-edition 2018 Breast Cancer Awareness Commemorative Coin and Stamp Set on Oct. 1, 2018. The set can be submitted to Numismatic Guaranty Corporation (NGC) and its stamp grading affiliate, Authenticated Stamp Guaranty (ASG), for certification with a special “Coin & Stamp Set” pedigree.
The set contains a 2018-S Breast Cancer Awareness Proof Half Dollar as well as a Breast Cancer Research stamp. The US Mint has capped the number of sets at 25,000 and announced a household order limit of 1.
Founded in 1987, NGC has certified more than 41 million coins, tokens and medals. ASG was established late last year to provide similar certification services for stamps. ASG uses a 100-point scale for grading the condition of a stamp.
