I just uncovered a trove of older U.S. stamps that I must have bought ages ago (pre-“Forever”) and forgotten about. A bunch of commemoratives and some small denominations that they don’t make any more.

I’m not a collector and would just as soon stick these on envelopes. But the USPS website doesn’t seem to want to tell me how much for the second and additional ounces after the first (55 cents). Do you know how much it is?
