A revenue stamp, tax stamp or fiscal stamp is a type of ahesive label used to collect taxes or fees on various items. Many countries of the world have used them, for documents, tobacco products, liquor, drugs, playing cards, hunting licenses and other kinds of things. While revenue stamps often resemble postage stamps, they were not intended for use on mail and therefore did not receive a postal cancellation. However, revenue stamps can display cancellation markings, three types being by manuscript signature of the person canceling the stamp (usually with date), by hand stamp identifying the canceling agent (also usually with date), or by punch; otherwise, they may be simply affixed to a product in such a way so as to be invalidated or destroyed upon its unpackaging.
