I traded some jetons for this chip at a Blast From The Past Show a couple of years ago.

What's unusual about it (other than being a plain large star design; only a few known) is that there are 12-notches carved on the edge that are evenly spaced on one side, and another 12-notches carved on the reverse side also evenly spaced, but staggering the other side. The pigmentation in the star (brown) is the same as the pigmentation in the carved notches on the edge.

The piece is coded ID-PO "STAR" with a value: P ($150-$200), assigned in 1999.
