ancient coins & trading tokens
Adam traded these from his friend Pradip, whose father was a collector of ancient Indian and Afghani coins.
The majority of these pieces originate from the Raja Raja Chola empire (1000 year old coins), and Mughal empire (500 year old trading token). A trading token was often a weight of metal gold, silver or brass, which was then traded for an item or service. The metal bars were cut by hand and then stamped by the maker. These tokens are brass.
