为了适应美国硬币交易中不断追求高品级的需要,美国钱币协会于20世纪70年代制定了《美国钱币协会美国硬币评级正式标准》(0ficial ANA Grading Stan dards for United States Coins,OAGS)。此标准由布雷塞特(Ken Bresett)及科索夫(A.Kosoff)编写,并已多次修订出版。目前,这一分级方法正在美国逐步推广,但现尚未得到国际上的普通认可。这一标准的特点是首先将币面品级分为三档:精制品、未流通品、流通品。然后在每品后缀有一定数字(3-70)以表示其品级高低。这一标准出笼后,由于较为明确合理,且市场买卖双方均有迫切统一标准的要求,所以很快为大家所接受。目前美国出版的书刊已全部采用该标准,其他英语国家钱币界亦普遍引用,非英语国家则参照后制定尽量接近的品相评级系统。
