Hi Bob, cracks on the F14 are very interesting. Attached are 3 pictures of F14’s all with different reverse die cracks, one of which is the same as your own piece. These cracks are of course mutually exclusive, so this means that there must have been 3 different reverse dies used on this rare variety. I also think that the piece sold by Colin Cooke in the Crocker sale may be yet another F14 reverse, but my reference picture is not high enough grade to be sure. On that coin there seems to be a different flaw running between the ship and a border tooth to the right hand side. Did any member happen to buy that coin and can put up pictures to confirm or otherwise?
