Short answer: A typical roll (coil) of USPS Forever Stamps contains 100 stamps. More details:

• In the United States, Forever Stamps are commonly sold in rolls of 100, though stamps also come in sheets or books of 20. This is the standard quantity you’ll see for a single roll.

• USPS also offers subscriptions for rolls of 100 stamps, reinforcing that a standard roll is 100 stamps.

• Some retailers list rolls as 100 stamps per roll/coil, especially for First-Class Forever Stamps with flag designs, though designs may vary.

If you’re shopping outside the US, quantities and formats can differ (e.g., rolls vs. sheets) depending on the postal service. For example, other countries’ services often offer stamps in rolls or booklets, with varying counts per roll or per booklet. If you tell me your country, I can confirm the typical roll count there.
