2 Baht - Rama IX Einstein Medal

Issued to mark Thailand's participation in the international commemoration of the centenary of Albert Einstein's birth — an event coordinated across dozens of nations in 1979, though Thailand's release came several years later under the Buddhist Era calendar year 2529. The delay was not unusual; Thailand issued numerous science and culture commemoratives through the mid-1980s tied to UNESCO-affiliated programs on staggered schedules.

Circulation in the usual sense was never really the point. These issues were produced for collector sets and rarely saw cashier drawers.
