United States Perfins Collection

United States · 1900 ·

This is a listing for a collection or lot of 1,326 United States postage stamps featuring 'perfins' (perforated initials or insignia). These stamps were officially punctured by corporations, businesses, or government agencies to discourage theft and control postage usage.

Perfins were widely used from the late 19th century through the mid-20th century as a security measure before the advent of postage meters.
