Counterfeit or real?

As a side about weight, I have a S-78 which weighs 9.6 to 9.7 grams, depending on the scale. At 9.7 gram it is 149.7 grains which is well short of the 168 grain standard. However; I have suspected it might have been struck on on a TAL token like the 1795 NC-2s and the heavier standard for TAL tokens is 151 grains.



Of course this one is heavily worn. But there are some explanations for an authentic, but underweight coin. But it is definitely less likely than the use of a metal with the wrong components or ratios than the authentic.

I missed the post about the subject coin's weight. If the scales are accurate, a trade dollar with EF details should weigh about 27g. My raw EF weighs 27.14
Anything under 27g is signifcantly underweight for so little wear.

 

tried to post a larger image of the upper rev. but no luck.

 

We need images of the OP's coin that are in focus and we need to be sure of what the coin weighs. All the guessing is worthless without that.

 

Not sure how familiar you are with scales. Those scales that utilize a tray for the item being weighed can also be used without the tray. That's the purpose of the Tare function. When nothing is on the scale, tray included (meaning off the scale), you press the Tare button and the scale will 'zero' out. Then you can place the item to be weighed directly on the scale without the tray. The displayed weight will then be correct. Assuming of course that you already calibrated the scale with a known standard.

 

I've seen lots of different scales and seen the problems with proper setup. I tend to use a jewler because they are used to using accurate scales for weights near that of coins.
