From the USPS price lists in the Postal Explorer DMM archive (Rates and Fees through 2008, Notice 123 from 2009; 2012 from Postal Bulletin 22325), each row cross-checked against the USPS Historian's letter-rate table and other USPS copies. Also carries the Historian's letter rates since 1863 and postcard rates since 1873.",

Prices are read from the First-Class Mail retail single-piece letter table: the Rates and Fees page of each DMM edition through 2008, Notice 123 from 2009, the stamped-letter price from the January 26, 2014 price list on, when Notice 123 began listing stamped and metered letters separately. USPS Domestic Mail Manual 604.1.10 sets the Forever stamp at this price. Every row matches the USPS Historian's table of 1 oz letter rates.",
