25 Dollars Greg Louganis

Greg Louganis won both the platform and springboard diving gold medals at the 1988 Seoul Olympics — a feat made extraordinary by the fact that during preliminaries he struck his head on the springboard, required stitches, and returned to competition hours later to win. What was not publicly known at the time was that Louganis was HIV-positive, a detail that would not emerge until his 1995 autobiography and which reframed the incident considerably in retrospect.

The Marshall Islands began issuing commemorative coinage in 1986 under enabling legislation designed to generate government revenue, producing dozens of sporting and celebrity subjects through the late 1980s and 1990s. Mintages were typically high and secondary market premiums remain modest.
