US Stamp Full Unopened Coil 441,448,486? Value?

Ive got this large coil. It appears to have 500-1000 stamps. It is a complete coil of green one cent stamps. Perf 10 horizontaly. They are either #441,448,or 486. Does anyone know how to tell which it is and its value? Thank you.

From the photo....
Appears to be rotary printing.
Thus eliminating #441.

With watermark #448
w/o watermark #486

My guess, based on color....
without watermark #486.

Let us know.

edit...spelling error

First, you can either rule out 441 or identify the stamps as such by measuring. 441 is a flat plate printing, if I read things correctly, and should measure 18.5-19 mm wide by 22 mm high. The other two stamps were from a rotary press and should measure 19.5-20 mm wide or 23 mm high. If your coil is one of the rotary press printings, you can rule out 486 if it has a watermark.

Thanks @KGB @kevin504 how do I test for a watermark without opening the coil, it is unopened? What do you think it is worth?

it most likely has 500 because they made those for those automatic hand stampers, its hard to put a value on something their isnt many of selling.

i found this on ebay http://www.ebay.com/itm/486-ROTARY-...141481028072

Man, a single mint, never hinged 448 must go for about 9 or 10 dollars. (Blackbook says even higher.) I don't know how one would price a coil. You could reason that one would just multiply by 500, but who needs five hundred of the same stamp? Some people might love having a never opened coil, but I wouldn't understand it.The logical--not emotional--thing would be to break up the stamps and sell them as strips of two or three (?).

As for the watermark, kev might be right about the color, but I don't know if a buyer would accept that kind of test. Hopefully someone here can tell us if there really is a value in keeping the coil unopened. If there isn't a good reason to leave the seal, then you can test the top stamp and show its result to prospective buyers.

After looking at recent, completed ebay auctions, it looks like a mint, never hinged 448 might go for five dollars.

How many line pairs would be in this roll?

Another question, would the centering change throughout the roll?

#486 is a very inexpensice coil single....

Roll looks to be opened.
A complete unopened roll will have a long brown leader
tab that wraps around the roll.

Line pairs are usually every 20??

Centering on this roll does not look to good.
You can see a LP at the beginning with the line
out of place.

Kevin504, that's what prompted both my questions for sure.

My hope is, that it might be possible that the centering could improve over the length of the roll.

What about paste up pairs?

stampcrow,
Due to the many manufacturing variables, the centering can vary along the entire roll. It appears to be rotary printed, so there won't be paste up pairs every 20 stamps. As Kevin stated, there will be joint lines every 20 stamps. I have no idea if a 500 stamp roll was produced in one shot or not. I imagine that they would be, but I hope that someone will answer that definitively.

Paste UP pairs are made from flat plate
printings being "pasted" together.

Think of a roll (cylinder) in rotary....
As long as the roll is turning....
it is printing.

Flat plate....think of a rubber stamp.
1 impression at a time....then piece together
end to end to make longer strips.

Hope I explained it simply.

I think he knows what a paste-up pair IS.
I think he wants to know what kind of premium attaches to it.

For me, the dollars alone don't do all the talking. Market is not the only basis for decision making. You need information that is not likely to come from here. But my comments could also be much ado about nothing.

Business aside, is there a greater philatelic value in keeping the roll intact or in breaking it? I suggest that before you break it you consult with some ranking specialists to see whether or not this roll makes any difference. Your best chance of reaching them is through an adlet in the United States Specialist, the journal of the United States Stamp Society. Before you break it up, consider giving a specialist student of coils a chance to examine it.

After they have a chance to examine it, if that is desired, they can advise you on how best to market it. I doubt that there are many intact, if not unopened, rolls left. But it's not my field and I don't have all the facts.

I hope Clark Frazier has a chance, and inclination, to weigh in on this before the dice are cast.

Yes, of course that makes perfect sense. *hand smacking forehead*
Thanks Kevin504.

DNA, so it would be possible, even likely, to have some XF even superb centering.
For me it's not about $'s, it's about uniqueness. Is a superb 98 single stamp more rare than a roll of stamps?

I like essayk thoughts about allowing an expert/student of, to spend some time with it.
