The arithmetic

Stamps at the Forever stamp price in Notice 123 effective October 4, 2026. These totals are arithmetic, not USPS store prices.
Quantity	Total	How it is worked out
1 stamp	82¢	Notice 123, stamped 1-ounce letter
Book of 10	$8.20	Arithmetic: 10 × 82¢
Book of 20	$16.40	Arithmetic: 20 × 82¢
Coil of 100	$82.00	Arithmetic: 100 × 82¢

That arithmetic follows from what the Domestic Mail Manual says about how Forever stamps are priced:

“Forever stamps are sold for the price of the current First-Class Mail single-piece 1-ounce letter price.”

USPS Domestic Mail Manual 604, section 1.10

“The postage value of each forever stamp is the current First-Class Mail single-piece 1-ounce letter price.”
