You're coin being a Bicentennial might bring a little more.The trick is to find the right buyer that just can't live without it in his or her collection.hope this helped

Thanks for the response and time Jasper...and theirs doesn't really look like a double...comparatively 

Is the date "clipped" with a defined edge. Looks a bit rolled to me.
Can you provide an edge pic?
