O.K., I am trying my hand at attributing large cents. This is my first time doing this, so I may be off in my analysis. I have a 1797 ANACS large cent that has been graded as VG8 Details. There is no Sheldon attribution on the slab. I don't yet have Penny Whimsy, so I am basing my attribution on the information on Tom Deck's site. Based on the obverse die crack, this seems to be a S-139. Do you think I have the right attribution?
