Absolutely not ... at least not in the US. The specific regulation is in the USPS Domestic Mail Manual 604 recited below under Paragraph 1.3(d) that states in part:
Quote:
1.3 Postage Stamps Invalid for Use
The following are not valid to pay postage for U.S. domestic or U.S.-originated international mail:
a. Postage due, special delivery, special handling, and Certified Mail stamps.
b. Stamps of other countries.
c. United Nations stamps, unless on mail deposited at the United Nations, NY.
d. U.S. stamps that are mutilated or defaced; cut from stamped envelopes, aerogrammes, or stamped cards; covered or coated in such a manner that canceling or defacing marks cannot be printed onto the stamps; or overprinted with an unauthorized design, message, or other marking.
e. Nonpostage stamps, such as migratory-bird hunting and conservation stamps, U.S. saving and thrift stamps.
