Although it is possible that a card room might use a chip like this I believe it is highly unlikely. Even thought it is a low denomination it could be easily be produced by anyone. Also if I am correct the reverse is blank making it even easier to produce.
If any firm confirmation is obtained that it was use as believe and I obtain same it will be included.
Sure wish there was a spell checker for this as typing one handed is for the birds.
Wishing all enough,
