Is this a fake coin?

I got this coin but I don’t know if it’s fake or not

N#3957 (Link to the coin)

it says in the link that the coin weighs 4.4 grams but mine only weighs 2.35

Please crop your image, we only want to see your COIN!

here are both sides

Reichs Stadt Achen? The year and the heraldic seem to be wrong!

The year is 1792 

Quukske

The year is 1792 

So you found the coin as well, it might very well be genuine!

Doesn't look like a fake to me
