Since January 1995, when the U.S. Postal Service raised its prices, the U.S. Postal Service made several stamps with the letter “G” that didn’t have a value. The first class mail stamp was worth 32 cents. They were used until 1998, when the rates were changed again.
On the stamp, there was a flag that was waving, the letter “G,” and one of three notes. On first-class mail with a white background, the phrase “For U.S. Addresses Only” was written. The background of the 25-cent First-Class Presort stamp for bulk mailers was light blue. The Postcard Rate stamp could only be used on postcards and cost 20 cents. It had a yellow background and was only for postcards. The Sun Sentinel says that there was a stamp that looked like a dove and was called “The ‘G’ Rate make-up stamp.” It cost 3 cents.
