US 3-cent Stamped Envelope with 1-cent Surcharge

United States · 1958 · 3¢ with 1¢ surcharge

A circular indicium featuring 'U.S. POSTAGE' and '3 CENTS' with a central bust design, overprinted with a rectangular 'U.S. POSTAGE 1 CENT' surcharge in the lower right.

This indicium reflects a postal rate change in the United States, where a 1-cent surcharge was added in 1958 to existing 3-cent stamped envelopes to meet new postage requirements, likely increasing the standard letter rate to 4 cents.
