Snerk. Messydesk has another issue to attribute. In all seriousness, I hope some day I'm as good at this as you are.
I still need to get one of these. I have my eye on one on Ebay, but it has a couple more zero's than I can currently afford.
My personal no motto one. Not the highest grade not the rarest date of the series but that's a heck of a coin for the money not a hard variety to attribute as there's only one set of business strike dies
These are quite a bit easier than Morgans. Worst case is something like 16 die marriages as opposed to 300, with a few being only one die pair like the 1850 above and a 46-O I have. Die stages may turn out to be significant, but some seem to be discernible only on high grade coins.
Morgans are just a concerted and coordinated effort between those who have the coins, and those who have the cameras and skills, from becoming far easier to attribute.
