I bought this lot number 33411958 on bidStart a couple of weeks ago-- price was reasonable, and I was taking a chance on the grilled 3c 1861 with the rosette cancel-- I have seen that cancel before on a D-Grill, and the back of the stamp actually has "85" on it.
I don't go by owner's marks on the stamps, but thought "what the heck", and some of the others might make the lot worth it in the end.
Received a cert back from Bill Weiss on Thursday-- #85 with several short perfs on the right side and natural straight edge on the left with fancy rosette cancel. Scott CV is just over $1000:

Enjoy! Ray
