Is Grading of Mughal & Princely State coins trustworthy?

[capnbirdseye]

I fully agree with ThCoins and ASM re paying for someone to give their presumed  "expert" classification of a hand struck coin.

I have been following and posting in a very long thread on Numista which involves gold Mohurs with Bahawalpur mint that the owner says his family have owned for 100+ years . Thought by the family to be Bengal Presidency I pointed out various unusual things about the coin, no rulers name, sana is written but no RY,all die identical etc.
As the thread went on he sent them off to an offline expert who clearly had no idea about hand struck coins and how they vary etc and points out inconsistencies of thickness and size. He denies paying for this service but I am not sure. The coin owner has shown assay certificate for gold content however. I did a colour code for the translation of the script for these coins, non of his offline Indian experts can read Persian script apparently even though Urdu is based on it.

Then very strangely the offline expert also has some of these gold mohurs as well 
The thread is long but take a look here:- NUMISTA and tell me what you think, one coin looks like silver to me and has Alamgir II on it but also Bahawalpur mint, all these coins are die identical, just varied position on the flan. Are they suspect?? I think some things don't quite add up

I can understand your frustration Vic ! Especially when the comparison is made with a similar specimen. (why would you care if it is a different type ?  )
You can just offer friendly advice. It is not possible to prevent that gullible people take the advice of the  learned snake oil salesman.
