Quote:The question of US Mint product codes have come up a couple of times, and with the publication of the 2018 schedule I think it can be confirmed that they follow a pattern. In 2016 the Mint standardized their Item (or Product) Numbers. (Prior to 2016 they seemingly put together a random letter or two followed by a sequence number, making it extremely difficult to backtrack a mint product from a product number.)
Mint Product Numbers are generally four or five characters, and take the form of:
YYTU

where:
YY is the year.
T is the type. Types:
A:
ATB QuartersC: Commemoratives
E: Precious Medals (includes all Eagle products and the Buffalo.)
K:
Kennedy halvesN:
Native American dollarsP: Presibucks (when they were produced.)
R: Regular (Maybe Repeating, since it's used for annual Mint products.)
X: Special Mint Product (See below.)
U is a letter that uniquely identifies the product. An exception exists for some
ATB Quarter products, where U is "B" for bags, or "R" for rolls.
V is only used if the product is an
ATB bag or roll, and is a letter that uniquely identifies a product. (Examples below.)
Special Mint Products:
Special Mint Products are US Mint products that don't involve congressional mandates. Examples are the centennial gold coins, The American Liberty products and the 2017 EU set. All are/were single year issues.
That probably means the 2018 1/10ozt gold American Liberty (18XF) and the 2018 San Francisco Mint Silver Reverse Proof Set (18XC) WILL ALSO BE SINGLE YEAR ISSUES. (Did I yell that loud enough? BTW, The SFMSRP set is to commemorate 50 years of silver proof sets. (That's sort of a misnomer, since all proof sets prior to 1965 were silver...)
