Proof Coin Or Not?

Your question raises another equally interesting question.

First of all let me observe that--I think--your coin has been pretty heavily polished. If you look at the main obverse device for instance, the high points have been rubbed shiny, while in the inner edge between the horseman and the flat fields there's still an outline of whatever substance was previously covering the coin.
I would generally assume that a coin that has gotten this kind of polishing-cleaning was probably never a proof coin. But the question that I'd be interested to hear more veteran members of the forum address is this: what does a proof coin that's been improperly cleaned even look like?

Best regards bobo13, and welcome to the forum!

Here is a web site which give some nice photos of the coin you have posted,

I agree with seriousceres, the photos that you have posted shows that the protected areas of the coin are dull in color when compared to the field. If you compare your photo to the web site above and look between the back 2 legs you will see that the whole coin should look like.

I agree with you, I have almost no experience with coins.
Thanks for your help!
