Some examples I guess I could have looked at prior to posting, but, with that said, like John mentioned, there is no true way of really placing value on it until you see what you get at an auction.
I believe mine is nicer than both the H&S copies but not the Heritage one so placing value somewhere in between is likely the safest bet?
