I believe that the post office will no longer be issuing first class-one ounce stamps with the price/amount on it (eg., 44¢ now). They will only issue forever stamps (for one ounce) that can be used forever for a one ounce letter. (Maybe this is obvious, but I once asked at the post office if one could put several forever stamps on one envelope, with all said stamps being valued at the current one-ounce rate, and they said "yes.")

Boris Karloff, Edward G. Robinson and James Cagney playing craps on a billiard table in "Smart Money" (1931). (Robinson is in the center. Karloff is left of him. Cagney, in striped shirt, is right of Robinson.) .. .. ... "Nick Venizelos (Robinson), an immigrant Greek barber, has an uncommon affinity for poker and other sorts of wagering and a group of his friends bankroll him in a big game, where his weakness for pretty blondes is taken advantage of by sleazy operator Sleepy Sam who cleans him out in a rigged game. Nick accepts help from his buddy Jack (Cagney) as they turn the tables on the grifters, but triumph soon changes to tragedy." per IMDb.
