1795 Half Dollar Value

I'll say PO-01, FR-02 at best, basically a hole-filler.

Best price for that coin is to find a dedicated lowball collector - they are few and far between but if that coin were in a TPG PO01 slab it would sell at auction for a lot more than as is and easily cover the grading fees.

Risky to try but the reward is there if the coin makes the cut.

Interesting coin. It looks like an Overton-128 (or what's left of it). The obverse makes Fair-02. The reverse barely makes Poor-01, but some of that may be due to strike quality, as well as wear. Because of the strong date, I'd net it upward to Fair-02. The deliberate scratches (graffiti?) on the obverse may detail the coin. I don't think it snags the coveted lowball grade.

As to price

It's heavily circulated, but it's still marketable. IMHO, you would have a better shot on a bourse floor than eBay. I'd be afraid of this one selling way below value on eBay. It will take the right buyer to bring good value here, and it's a lot easier and less costly to say "no" on a bourse floor than on eBay.
