US Post Office question: How much are "H" stamps worth?

Answer 1

The "H" stamp is worth 33 cents, and the "H rate makeup stamp" is worth 1 cent.

They're still valid postage if you combine them with enough other stamps to make the rate you need. So for a regular 41-cent letter, if you put an 8-cent stamp on as well as the 33-cent one, it will work, and you can probably get 8-cent stamps at the Post Office.
