Russ, sorry to bring you down to earth , but ... If you look at an earlier post I did of a previously undiscovered reverse variety (unquestionable) of an 1887 wreath reverse sixpence, you will agree with all my evidence that this is a clear variety. However, no-one has expressed any interest in it, from Spink downwards. The main reason being (I suspect) that there is only this one specimen. Ironically, fi there were a few others it could be classed as a rare variety, enter the books, and make me a modest fortune. You're in the same boat. EVEN IF it turns out to be a 1 for I variety, without any other specimens you're on a hiding to nothing, and it's very unlikely anyone will take any interest. Sorry, but that seems to be the way of the world with coins.
