Two 1c Franklins Off Cover, Still Not Great At Identifying Types

I'm still going through these boxes of stamps I inherited and found these two Franklins. I've been looking at stamp smarter and the other resources but I still have a hard time identifying the types. So again, any help would be appreciated!

Both Type IV.
Imperf one is #9, Perf one is #23.

Thx txstamp! You really seem to have these down! Are you involved in the playing of these types of stamps?

I also found this attached to another stamp, the other one is kind of pieced together. I don't have a picture now. They were both on a cover but there was clearly a third stamp that had been cut out. I'll try to get pics of the cover and other stamp.

The left-half stamp piece you posted looks to me as though it came from Plate 11. The cancellation dot at 9PM in the colorless oval narrows it down to Plate 11 or 12. To me this looks most like a Plate 11 A relief, but that plate is weird enough to where it could be a B... Either would be a Ty IIIA, Scott #22, top line broken.

To answer your question, yes I've spent time plating 1851-issue stamps - especially the 1c. There are a number of other 1c & 3c 1851 platers on this board.
