Various tin pitis, mostly types with a hole in the name of the Sultan Baha-ud-din (1776-1803) of Palembang, but other types are also included. The coins are 17-20mm or so, 0.5-1g+. Very nice quality coins, most or all of retail quality. A few years ago these coins used to be retailed for 30$+, though now there are a lot of them on the market. Very nice study group - there are numerous varieties and dates, the group is unpicked and unsorted.  The coins are mostly pitis coins with a hole, but there are octagonal and Chinese-style coins, and early 19th century pitis without a hole. There are numerous varieties of these (described in Millies). The condition F-EF, with most coins on the better side. A few coins are damaged, but 90%+ of these are good enough for retail.

18 USD for 5 random coins.

Palembang is a city in Sumatra, Indonesia. It was once a Portuguese colony, and later the seat of the Sultanate of Palembang. These coins used to be quite rare and expensive, until a number of large hoards made them generally available and relatively cheap.
