Not sure if any of these will help the plating specialists, but here's what I have. If I have the position, I'll state it, otherwise, I'm not sufficiently versed in the intricacies of plating these to be much help.
The first one is Scott 9.
The next one I'm not sure about. I feel the side ornaments are more complete than Type V and tentatively have this as Scott 21, but that's open for debate.
The remainder of these are Scott 24, I believe.
Next is one of my favorites in this group. It is unused, no gum, Scott 24. Position is 78L10. APEX certificate follows:
The next copy is a straddle pane example.
The next stamp is faded, but I loved the 1860 dated cancellation.
The next stamp is well centered with a nice bars cancel.
This stamp attracted my attention with three nice margins and light cancel.
The last single stamp is this one with a great blue cancel.
Now for the covers.
First up is a nice little cover. I particularly liked the 1861 dated cancel and lightly applied circle of bars killer, as well as the petite size of the cover.
The next cover used three one cent stamps to pay the three cent postage to mail this cover.
The final item is a very attractive, at least to me, carrier rate cover using Scott 24 and Scott 26.
Hope some of these help with the plating guides.
