The one I referenced above sold for $79; but more research would be necessary to determine, if possible, the mint and the exact variety. Only then (IMO) could a value be determined more precisely. Then again, due to the condition of your coin, the mint may never be determined; it would appear as initals in the exergue on the reverse side.

No problem!'lazooro' did the 'heavy lifting'; I only did the 'clean up'.
