The listing, USA #2877 1994 Peace Dove on G-Rate Make-up rate stamp, mint has ended.
USA stamp featuring a dove of peace. This is the "G-rate" make-up rate stamp. When postage increased from 29c to 32c in 1994, they issued "G-rate" (32c) stamps. This stamp was designed so that people could use up their older 29c stamps along with this stamp to pay the 32c rate. At the time, since they did not always know ahead of time what the new rates would be, they simply called them "G" rate (it started with "A"-rate stamps in the 1970's).
