club cal neva in reno odd casino item indian tahoe las vegas ball marker frank

Description

oddball casino item only about 3/4 of an inch across
read condition description - 12 included
i submitted these to a couple of different casino item experts and they were unable to figure out what they were. i am not aware of the cal neva ever having had a golf course, so i don’t think they are ball markers, but they would work as such.
the going consensus from the experts was that they are not ball markers but they are unsure what they are
if you know, please let me know! i’m still keeping a few for myself and would love some history
