It is a teetotum.
Driedal type spinner. Go ahead ,spin that thing between your thumb and index finger to get it going. Let it wobble eventually by itself ,then fall.
Might be for a put take game.
0 is showing in the right picture,that means take nothing from the pot. (Pot starts from players ante's,plus from when they land on a P "put".) The P3 showing in your picture would be put 3 in the pot.
To the far left showing in the one picture is T2 . Which is take 2 from pot.
I don't know what the star is . Jewish symbol maybe. TA=take all is indicated as one face on some put take spinners. Maybe the star means that.
Due to the star ,for further research I'd suggest looking up Jewish Driedal dies. Or spinners. Ect.
