Ordinary Forever vs. Postcard Stamps
| Product | Postage category | Typical use |
|---|---|---|
| A Day at the Beach, Protect Sea Turtles, Sharks and National Marine Sanctuaries | Ordinary Forever | Eligible domestic First-Class Mail one-ounce stamped letters |
| Coral Reefs and Sailboats | Postcard-rate stamps | Eligible domestic postcards at the current postcard rate |
The shared ocean artwork does not make these postage categories interchangeable. A Postcard stamp contributes its current postcard-rate value; it is not an ordinary one-ounce Forever stamp.

- Wildlife and conservation: compare Protect Sea Turtles, Sharks and National Marine Sanctuaries.

Frequently Asked Questions
Are every stamp on this page ordinary Forever postage?
No. Coral Reefs and Sailboats are Postcard-rate stamps. The remaining listed designs are ordinary Forever issues.
Can a Postcard stamp be used on a letter?
It can contribute postage, but one Postcard stamp does not by itself equal the current ordinary one-ounce letter rate. Add enough valid postage for the finished mailpiece.
Does an ocean theme affect mailing validity?
No. Validity and value come from the postage category and the stamp’s condition, not its artwork.
Are all sea-life stamps included?
