No, not the same size. 

Though it's true the second is a duplicate of the unknown country one.

I would consider them the same. Gaming tokens are cheaply made and were mass produced. Coins have a tolerance of 0.5 and these gaming tokens are not produced to the same quality standards as coins. So a difference of 1.5mm in diameter, 0.62m in thickness and 0.98g in weight is not an excessive amount to have a separate page. And that is assuming the information was entered in correctly or the instruments used are decent tools.

I agree about low tolerance on gaming tokens, but this is interpretation. Guidelines states that “The same type may include: (…) Small diameter, mass, shape, and thickness variations, especially for ancient and medieval hammered coins” but with no tolerance clearly indicated. How “small” variations should be accepted ??? A solution would be to indicate a numerical tolerance, or many: one for modern coins, one for ancient, for tokens…

The 2 page have been created same time by same member, let's assume the difference between the 2 tokens is real, even if the measurements contains an error

Excluding thickness, I think the feature “Register an example of this type” eliminates these minor differences. Thickness can be added to the comments.

Done, the other three are different a bit.
