1c 1851 Plate 4 Stamps

A nice find: 5L4. Might be unused (there is some possibly suspicious toning/discoloration in Franklin's head), but a nice stamp either way.

Great looking stamp Dudley!

dudley - very nice.

I'm always grateful for that nice, consistent horizontal scratch across 4-5L4. It sure helps in plating these.

43L4




Red is marks shown in Neinken

Green is additional marks shown (more clearly) in Doporto

Yellow is another consistent dot.

I've been stuck on this one now for a few weeks.

stallzer, plating marks on Plate 4 stamps are notoriously fickle. This example appears to be a B Relief. I suggest checking 16L4--the Doporto archive images of 15L4 and 26L4 may provide some support.

I see some overall resemblance to 12L4 including the dot inside A and the dot above O. Can you see through the cancel to see if there is a dot above T?

I would agree with the 16L4 that Dudley suggested.

Appreciate all the help and input.

I didn't like the 16L position. Both the Doporto site and Neinken show a plating mark in and near the "P" in postage that is absent on mine and the Neinken diagram shows what should be an obvious plating mark on the North side of ornament A which is also not present on mine.

15L4 should show various plate scratches (from Neinken) that are not shown on mine.

26L4 is a C relief and I am stuck on a B relief. I'll dive into that one further hopefully tonight or this week sometime.

NJS, 12L4 I do believe I can see the plating mark (dot) above T. I'll try and zoom in on a scan and post it here shortly.

Plate 4 is certainly a challenge, for everyone. 12L4 is not a Type III, IIIa changeling so since yours has the bottom frame clearly broken and 12 doe snot I would tend to look elsewhere. I put together this visual of Dudley's suggestion of comparing the pieces of 15L4 and 26L4 (the left and lower neighbors of 16L4) which are party shown on your stamp. They appear to match up very well.




The mark in the P of postage on Neinken is sadly not visible on your stamp due to the cancellation. Hope this is helpful.

Don't forget that plating marks on Plate 4 stamps can be fleeting. Plus I think I see the mark above the P where there is a break in the black cancel.

Here are close-ups of the upper parts.





For NJS, here is a close-up of above T.

Here are some of the marks I was hoping would lead me to an answer but I've obviously been unable to find a match

I'm a sucker for wide margined imperforates, and although I already owned a nice Scott #8, I couldn't pass on the opportunity to buy this one. It was plated on a 1998 PF cert as position 54L4, and it was pretty easy to confirm from plate marks and the lower right guide dot.
