Watch List notes:

SAMANID: Yahya b. Ahmad, 927-931, AR dirham (3.34g), Nishapur, AH319, A-A1454, EF, RRR. This appears to be the second known example, the first selling in a Baldwin's auction in May 2002. All coinage of this ruler is extremely rare, the silver more so than the gold.

Estimate: 1,000-1,200 USD
