Is this Palembang coin authentic and what is it worth?

A seller online is selling this coin which appears to be https://en.numista.com/catalogue/pieces85525.html. I find this to be an interesting coin but I want to know if it is authentic. Also, what would be a good price to pay for it? Since one side is blank (and the photo of that side is very dark), I only provided the photo of the front).



Thanks.

It's a common coin and as it's in Tin you might not expect a better state.
Between 1$ and 5$
