BUY IT NOW! U.S. Revenue Lock Seal Liquor Stamp,  LS81D, Series L used

Used stamps have the area of the perforated diamond punched (cancelled) by the key when inserted into the lock. Most of the used examples I have have been reinforced by a hinge. You can easily soak these off.

Lock seals are not tax stamps, but were used in enforcement of tax laws and are thus considered by many collectors as part of the taxpaid field. Lock seals were inserted into special distillery warehouse padlocks to cover the keyhole and make it impossible to remove liquor without proper control and taxation.

Thanks for looking. Please check my other auctions for more lock seals. I combine shipping!
