What Do You Think Of These Imperfs And Part Perf?

A friend of mine sent me these scans this morning. I think the R13a could possibly be good (thin paper, would come down to impression), the R13b no (maybe a photographer precancel, thicker paper), and the R3a probably a trimmed margin copy (dull red, date a bit late).

What do you guys think?

The R13a seems possible, I'm only concerned about the possibility of a perf dent at the top left corner.
The R13b looks suspect for certain. Right side is not a straight cut, and there appears a perf indentation about mid way down.
The R3a with its wide margin could be a bottom corner stamp. Would need to examine it to be sure, but because of those wide margins I'm suspect.

This is a certified copy of R13a.

The margins and color on yours seem to be pretty close to this one.

I think that it should be worthwhile to look into obtaining a certificate for your copy.

No, no, absolutely not, in that order.

maybe, no and no.

Not on a paper with that much mesh, and not with margins trimmed in this manner. And large scans make the margins appear wider then they actually are.

The reverse scans show that all three are on the wrong paper.

Thanks guys, I appreciate the feedback!

Genuine R13a are a very thin almost translucent paper, the majority with Wells Fargo cancels.

All the blue first issues (2, 10, 50 cent, $1.50, $3.50, $15) all come on a very thin hard white translucent paper with no real mesh visible. The design is usually fairly clear even from the reverse, even when face down flat on a table. Generally the red values (5, 25, $1, $5) have a slightly thicker paper, but still thin with no real mesh. I have long wondered whether this was deliberate based on better overall results or just the luck of the draw.

The $10 stamps (both perf and imperf) can also be found on a very thin translucent paper similar to that used on the stamps above.

The major difference here is that while all these other denominations/types *CAN* be found on that paper, the R13a can *ONLY* be found on that paper.

Pretty much all the imperf and part perf blue stamps are only found on that paper. The higher values above 50 cents had relatively few printed; I suspect they were all done at about the same time. And no one really knows exactly how long imperf and part perf stamps were shipped out.

R5a and R5b are found on a thicker more opaque paper than that of R13a. The latter is a very distinctive paper.
