Around June 2003, I wrote:
But a better idea is what I call the “letter rate” stamp — stamps that don’t have a dollar amount on them, but are good for mailing a letter, forever. Buy as many as you want at today’s rate — when the rates go up you don’t have to bother with penny stamps or worse, returned letters. The post office would certainly make more money from people buying early. Probably makes too much sense though.

This Stamp Could Be Mailed ‘Forever’ — The Postal Service is planning a “forever” stamp for letters, good no matter how many times postal rates increase.
Three years. I’ll take it.
