Hah! I could use Forever stamps!
Just tell them to take the stamps at their value in 2015.
I did find this other posting on another forum about pennies.
Presumably, a debt, large or small, can be paid in any sort of Congressionally-authorized currency (or money or coinage or whatever term you
like). There used to be, more than 20 years ago, a law that said that payments above a certain amount (like $20) could not be paid "in minor coins"
-- this was deliberately concocted to prevent those spiteful payments of taxes or alimony with tons of pennies; but this provision no longer appears
in the US Code.
Arguably you could, now, pay your taxes in pennies. But there are machines that can sort and count bushels of coins in a minute, and in return you'd
have to lug around hundreds of pounds of coins at considerable trouble and expense to yourself.
I still figure if I just pay my property rent^H^H^H^Htaxes with them it will be well worth the personal inconvenience.
