The story of the 2018-S
Collector-only production (2002 to 2025)
From 2002 the Mint stopped releasing halves into circulation and struck them only for collectors, sold in rolls, bags and sets. Mintages stayed between about 1.7 and 3.8 million per mint through 2012. In 2014 the Mint marked the 50th anniversary with a 1964-2014 dual-dated gold proof from West Point, 73,772 struck, along with silver versions from all four mints.
Silver proofs switched to .999 fine silver in 2019. Output for collectors rose again after 2020, with Philadelphia striking 30.2 million in 2023. Business strikes of these years are rarely found in change, so most surviving coins are uncirculated, often still in original Mint rolls or packaging. Silver proofs of the 2020s were made in smaller numbers than those of earlier decades.
Elsewhere in US coinage in 2018
The American Innovation dollar program began, with a new reverse for each state and territory celebrating an invention or innovator.
How to recognize it
Gilroy Roberts' portrait shows John F. Kennedy facing left with LIBERTY above, IN GOD WE TRUST below and the date at the bottom. The reverse, by Frank Gasparro, is based on the Presidential seal: an eagle holding arrows and an olive branch surrounded by a ring of 50 stars. The mint mark was on the reverse in 1964 and has been below Kennedy's neck since 1968.
