Indonesia, Teluk Samawi,Sultan Jauhar Al-Alam Shah, Tin alloy pitis,

[EWC]

I suppose that's a scarce coin ? may be others are sleeping in some trays, waiting an accurate label...

Yes - well done indeed.

The Mehrabanid coins tend to be part  lead, and tend to corrode a bit in the soil -  but often coins from around the Philippines etc tend to be tin and corrode away to nothing in the soil. 

Very rare coins – (often not in Sarang Singh) suddenly became common after the dredging of Palembang harbour, because, exceptionally, they were preserved in anaerobic mud.  But I never saw this one – and it is perhaps very rare indeed?

A new category for Teluk Samawi has just been added by charm, There is just one other of this type posted 10 years ago which was listed under Aceh but now put together with mine

Zeno - Oriental Coins Database - Teluk Semawi, Sumatra, 1226 AH

I noticed that the coin in Sumatra old city museum (the one of the link) is wrongly dated 1229 AH, all 3 coins are dated 1226.
