100 Riyals 2006 Asian Games, Khalifa Stadium

Qatar hosted the 15th Asian Games in December 2006 — the first Gulf state to do so — an event that required roughly $2.8 billion in infrastructure investment and effectively began the country's transformation into a major international sports host. Khalifa Stadium, originally built in 1976, was substantially renovated for the occasion.

This issue is one of several gold commemoratives released by the Qatar Central Bank for the Games, each tied to a specific venue. Mintages across the series were tightly limited, with distribution handled primarily through the banking sector rather than open philatelic channels.
