Are Postage Stamps Legal Tender?
Postage stamps are a way to prepay postal services. They are not U.S. legal-tender currency. Their valid postal value pays for eligible postal services; it does not turn them into cash for ordinary retail purchases or debt payment.
Postage Is Not Cash
A valid stamp can pay for eligible postal service according to its printed denomination or service category. That does not make it a coin, Federal Reserve note, bank deposit, or legal-tender payment for ordinary debts. Whether a private business accepts cash, cards, checks, or another payment method is a separate question and is outside this article.
Why People Confuse the Terms
Stamps display monetary amounts, can retain postal value, and can be privately bought or sold. A private party may agree to accept stamps in an exchange, but voluntary acceptance does not change their legal status.
Four Values to Separate
- Denomination: printed amount on a fixed-value stamp.
- Category value: current service value of a valid category stamp such as Forever.
- Resale value: what a buyer offers after costs and risk.
- Collector value: market value of a particular philatelic item.

The answer is limited to the legal status of postage stamps and does not give a universal rule for private retail payment policies.
