Watch List notes:

BENGAL: Nasir al-Din Mahmud, 1433-1459, AR tanka (10.45g), NM, AH845, G-B424var, obverse exactly as B424, but reverse similar except for fi sanat 845 below, same marginal decoration, one testmark on obverse only, perhaps rare, EF, ex John Page Collection. The 84 of the date is boldly clear, but the rinal digit is somewhat vague, probably 5 re-engraved over either the number 2 or 3.

Estimate: 100-150 USD
