I Think A 1 Fanam From Cochin

Not really. I just want to make sure my attribution is correct. A lot of the subtleties of the Indian culture can escape an outsider.

I have read that there are fakes of fanams, in good gold.
I guess a lot of those would be jeweler's copies sold into the Indian domestic jewelry market.
Indian ladies love their gold trinkets.

I think that may help to explain why the dealer didn't want to waste his time, trying to identify it.
He would have had a reasonably clear conscience, because at least he would be fairly confident in selling good gold. And what he didn't know about attribution would have left him in ignorant bliss. In his own mind, there was always the chance he was selling a genuine coin.

These diminutive gold pieces were made over the last four centuries and the task of attribution can be monumental. Even if you get a pictorial match with a genuine one out of a catalog, you still need an expert to prove that your fanam is a genuine one, rather than just a jeweler's copy, albeit in good gold.

I have to humbly admit, that I am in much the same position as the coin dealer.
I think have a couple of jeweler's copies in good gold. They were in my collection for over 20 years before I became doubtful of them, and I am STILL not certain that they are jeweler's copies, or are in fact, genuine.
