Octagonal coin, unread unknown inscriptions. 21mm, 1.11 grams. cf. Zeno 308481 (same type)

High grade, nearly mint state.

This type is similar in style to the tin pitis of Sultan Anom Sri Ingalaga (1742-1783) of Jambi Sultanate (in Sumatra, modern Indonesia) (cf.  HCM# 177-181) but the inscriptions are different. Interesting and unresearched type.
