This is not a coin appraisal site. If that's all you want, there are other sites that might better serve you.
It is worth whatever someone is will to pay you for it. Only a fool would tender an offer without seeing it.
To get a ballpark AU value, one can average out the $110 XF catalog value with the $300 MS60 catalog value, and the number is $205. (Since AU falls between XF and MS.) That's just a general rule of thumb, of course- take that number with a grain of salt. More for an attractive example. Less for a not-so attractive one. At least you're talking about an actual historical coin now, instead of some modern gimmick coin that's been colorized or plated or had rhinestones stuck on it or gawd knows what tacky things, outside the mint.
