Description:- Official Mail stamps are genuine postage stamps, although they were never available at any post office. These unique stamps are called Officials because their use was strictly limited to government mail. Before 1873, government agencies had “franking” privileges. This meant that government mail could be sent free of postage as long as it bore an authorized signature on the envelope. As of July 1, 1873, “franking” privileges were discontinued and special official stamps were put into circulation for use on government mail.
