5 Sertrum XXV Summer Olympics

Bhutan's Olympic commemorative program of the early 1990s was produced under contract by foreign mints — Bhutan has never operated a sovereign mint of its own — with distribution handled largely through the international coin trade rather than domestic circulation. The 1993 issue anticipates the 1996 Atlanta Games, not the 1992 Barcelona or 1994 cycle, making the timing a straightforward pre-issue marketing piece aimed at collector markets in Europe and North America.

The .5833 fineness is characteristic of Bhutanese gold commemoratives of this period, a non-standard alloy by Western conventions but consistent across the kingdom's numismatic output through the 1980s and 90s.
