How Much Are Forever Stamps Worth in 2026?
A Forever stamp is worth $0.82 in 2026
Every Forever stamp is worth the current USPS First-Class letter rate, no matter what you paid for it. As of the July 12, 2026 rate change, that means each Forever stamp is worth $0.82, and a full book of 20 is worth $16.40. A Forever stamp you bought in 2010 for 44 cents mails a letter today just the same as one bought this morning.
Current values for every Forever-type stamp
USPS prints several stamps that work on the Forever principle, each pegged to a different mailing rate. The words printed on the stamp tell you which one you have:
| Printed on stamp | Covers | Current value |
|---|---|---|
| FOREVER | First-Class letter (1 oz) | $0.82 |
| ADDITIONAL OUNCE | Each ounce over the first | $0.29 |
| TWO OUNCE | First-Class letter (2 oz) | $1.11 |
| THREE OUNCE | First-Class letter (3 oz) | $1.40 |
| POSTCARD | Domestic postcard | $0.65 |
| GLOBAL | International letter (1 oz) | $1.75 |
Why Forever stamps gain value over time
USPS introduced the Forever stamp in 2007 at 41 cents precisely so customers wouldn’t need filler stamps every time rates rose. Since rates have increased roughly once a year recently (the July 2026 change took the letter rate from $0.78 to $0.82), any Forever stamps sitting in a drawer have quietly appreciated. They never expire and never need topping up.
What are Forever stamps worth if you sell them?
Unused Forever stamps have a real resale market. Stamp buying services like ours purchase them at a percentage of face value, so a large quantity, inherited sheets, leftover office postage, or an abandoned collection, converts to actual cash rather than sitting unused. Condition matters: full books, sheets, and rolls in clean condition are worth the most. See exactly how it works on our sell stamps for cash page, check what your other stamps are worth on the current stamp values chart, or read whether you can sell back unused stamps (short answer: USPS won’t buy them back, but we will).
How to buy Forever stamps
Buy them at any Post Office window or kiosk, on USPS.com, or at most grocery stores and pharmacies. The price is the same everywhere: face value, currently $0.82 each. If rates are about to rise, buying ahead locks in the lower price, which is the whole appeal.
