Ancient tokens

[C_jami]

I recently found this two "tokens" in a old box I buy from a market in Amsterdam. One is clay and one is a type of rock
Dose anyone recognise this ?

I initially thought "petrified biscuits" and instantly realized how unlikely that would be. Then I read the description. Yeah, it's a game piece and that's obvious. Is it checkers? Probably.
