Brewer's: Twopenny Dam
(A). A dám was an Indian coin and weight. Originally a gold mohur contained sixteen dáms; a punchee was = the quarter of a dam, and a bárahgáni = half a punchee. Putting this in a tabular form, it would be thus:
2 bárahgánis = 1 punchee.
4 punchees = 1 dam (worth in its diminished value about 2 pence).
16 dams = 1 gold mohur.
