What is a First Day Cover ?
--When every new stamp (or stationary item) is issued, most generally, just one post office in the entire United States is designated as the one city that can sell the new stamp design on that first day.

--A special postmark/cancellation that reads "First Day of Issue" is prepared with that one date ONLY and ONLY for that one post office.

--That postmark/cancellation is applied to the new stamp on envelopes (or on a miniposter as shown on the right), known as covers.

--This special cancel certifies that each cover is a limited edition which can never be duplicated at any later date.

--Each first day cover (FDC) is enormously educational and an historic collectors item that will be treasured for generations!

--Some FDCs produced by PUGH CACHETS, INC.
have sold for up to 7000% of their original issue price.
