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. Compiled by The Reseller Index from archived USPS price lists and other USPS documents: the price periods, gaps and cross-checks are ours, each price is USPS's, and each row links the USPS document it comes from.",
