Hi, ZacUK. Thank you very much for your valuable input.
You are correct — the token you referred to is a variant of the one I posted.
The differences are not limited to diameter, weight, and metal composition; the lettering style and ornamental details also vary.
The sellers you mentioned describe this token as being used for video games, which reinforces the hypothesis that it was intended for amusement purposes.
Another seller lists the same variant:

However, the dimensions match those of the token I originally posted.
Although I still cannot confirm its actual use, it seems we are heading in the right direction.
Many thanks again for your assistance and insights.
