Watch List notes:

BENGAL: 'Ala al-Din Husain, 1493-1519, AR large flan tanka (10.60g), Dar al-Darb, AH912, G-B761, bold strike on broad thin flan, 5 banker's marks along the obverse margin, struck from slightly worn dies, superb EF. This is the only well-known broad thin tanka from any of the later 15th and early 16th century sultanates. Its purpose of issue is unknown, but the frequent use of banker's marks suggests that they entered general circulation. Dar al-Darb means "house of minting", and does not refer to specific location.

Estimate: 200- 240 USD
