My photo of this type was posted above but I want to make clear that this coin is not a counterfeit. Counterfeits are made to fool fools and are aimed at providing something less than an original. This is money of necessity intended to be better than the real thing in a place that could not get enough proper denarii to met demand. When Rome started debasing denarii in or around the time of Nero, it went over like a lead balloon in some places that had come to look upon Roman denarii as trustworthy. The result was some local imitations made not to deceive but to provide circulating silver of the expected purity and weight. Some might call it a token of the class we see later in 'Hard Times' or 'Civil War' but since these were made to circulate outside the Roman Empire, it might be better to call them a Trade coin rather than a token. I suspect they were made in the first century AD but after the time of Tiberius. Your coin has a small chip so it may be a bit under my coin which weighs 3.63g. I have never seen one less than the high 3.5's so I suspect your (with chip) would fall around that weight. I posted my page on it a dozen years ago:

You should sell the coin if you consider it a counterfeit. You were correctly advised that they tend to go for about $100 (again the chip might have some effect). The existing supply of these entered the market about 15 years ago and number somewhere in the range of 2-3 dozen. There are people who appreciate the subject who should be willing to buy it for more than you paid but I can't imagine what kind of 'real' Tribute Penny you will get for $100 these days. There are other Indian copies including gold aureii (which often have twin holes at the top since many of them seemed to have been used as decorative items later on).
I wish you well and especially that you stick with the hobby long enough to appreciate a coin of this nature for what it is. Someone looking for one may have trouble finding it but both supply and demand are very small.
