A standard book of 20 ordinary Forever stamps represents $16.40 in postal face value at the $0.82 rate effective July 12, 2026.
The calculation
Multiply the number of stamps by $0.82: 20 equals $16.40, 40 equals $32.80 and 100 equals $82. Confirm the actual count because not every booklet contains 20.
Face value versus checkout price
A seller can charge a different total because of shipping, packaging, promotion or a collectible premium. Record the seller and date when comparing.
