(Counterfeit?) Guinea coin, George II [opgelost]

I need help identifying this coin. I bought it at a antique shop, but the owner could not provide me any more information apart from what it is shown in the coin. I have spent many hours trying to find any kind of information on the internet, but I found nothing, so I suspect it may be a counterfeit coin. Even so, I was hoping someone in here would know something about it.

In the upper part of the obverse (above the letters "in" in "Guinea") a 3 is barely noticed, I don't know if in the picture it will be clear enough but I think it is there. Also, mint mark (?) W. In the reverse, it is shown the head of George II facing left. Coin alignment. ~2cm diammeter, couldn't manage to properly measure the edge but it is pretty thick for a coin in my opinion. Unknown material.

Thanks in advance.

coin weight?

I don’t have anything to weight it at the moment.

The first reply was making a guess that it IS a coin weight -
the member was not asking what the weight of the item is.
I also think it is a coin weight - used on scales to check the weight of coins to
see if they are not fakes made of lead and so on, as there would be a weight difference.

​Oh okay, I see

Do you know where can I find more information about coin weights, such as its value?

EDIT: sorry, didn't see your last post with those links. Thank you!

I see it is not on Numista, I only found this link. If anyone gets any info on this coin weight, I would greatly appreciate it.

​Zac, I see you are the Exonumia Master Referee. As I said in the previous post, this coin weight is not on Numista. Could this be added in the catalog?
