Postage Due stamps were authorized in 1879 and were unique, since they were the first stamps issued which didn’t prepay for the delivery of mail. Instead, they denoted the amount of postage due on mail that was insufficiently prepaid. This amount was paid not by the sender, but rather by the recipient of the letter.
