The United States Mint has 5 products opening for sale in May 2026, across 5 programmes. 4 of them carry a stated product limit.
What is limited in May 2026
The Mint flags a product as limited when it has set a product limit, meaning a stated maximum it will make. A limit is not a mintage figure: the Mint often sells fewer than the limit allows, and the number that eventually sold is what the secondary market prices against. Treat a limit as a ceiling rather than a count.

Where this list comes from
Every date, mint mark, catalogue number and limit flag here is read from the Mint's own published product schedule, not from a dealer newsletter or a forum round-up. The Mint revises the schedule during the year, and a product can move or arrive without a date having been announced, so check the product page before planning a purchase around a date more than a month out.
