500 Tenge Taj-Ul

Kazakhstan's "Taj-Ul" issues belong to a series celebrating the sacred architecture of the Islamic world, commissioned by the National Bank during a period of aggressive expansion in its precious metal commemorative program. The 3.11g weight — exactly one-tenth of a troy ounce — was a deliberate choice to keep entry pricing accessible while maintaining .9999 fineness, a purity standard the Kazakhstani mint adopted partly to compete with established bullion programs from Perth and the Royal Canadian Mint.

Mintages for this series ran low, typically in the low thousands.
