Anybody know what this is?

solid, about as thick as a penny. almost looks like copper around the edge of it. Had it for a few years now, believe my grandpa had it in some coin collection

That's some kind of old school logo. Is it heavy? A weight?

If you're 82k years old what was the best part about prehistory that we dont know because our records were lost.

you have 80,000 years of prehistory. Give us a run down please on any time period.

That could totally be a unit of currency is some old school and lesser developed place. I dunno. the marking has (for me) an eastern european vibe.

chaos sigil?

Yep

It's a little complicated but could also be a money symbol like "$".

Its about as heavy as a quarter, may a little more

I've looked through Roman, Greek, Freemason, hobo, and straight up old symbols and have found nothing similar .

or a C M and maybe an O?

Not yours you Nigger
