Stamps (Philately)/imperforate


QUESTION: recently purchased multiple rolls (Forever- flags) and one of the rolls has no perforations - beginning to end.  Rare or return?

ANSWER: Hi Robert,
I apologize for the delay, due to a family emergency.
Robert, although I am not sure exactly which stamp you a referring to, any roll of stamps without perforations is an error and definitely should not be returned. Depending on which stamps they are it may be a new find. The value for errors is very speculative and can vary quite a bit. If you could do a follow-up with a clear picture I might be able to give you a better idea of value. And also a better idea how to proceed.
Thanks again for the question,

Hi Robert,
Thanks for the picture.
This stamp was issued in 3 different varieties, only one is known with the imperforate (technically called die-cuts omitted) error. The easiest way to identify it, since you have a complete roll is by the Plate number printed at the bottom of some of the stamps in the roll. The roll will have from 2-4 plate numbers (all the same), I'm not sure exactly how many on this roll. You will have to partially unroll it carefully to check the number. If it is plate# S11111  then it is the known error and listed in the Scott Catalog as Cat# 4868b as a die cutting omitted pair. Because these are fairly new (only issued in March of 2014) there is no value listed for it yet.
Robert, as far as a value it is a little difficult to tell, as the EFO (Errors, freaks and oddities) collectors market is very speculative. But if I were to use some other recent die-cut omitted errors as a guide, and the current market conditions, I would estimate a realistic retail value of from $50-$80 per pair, with a premium for strips of 6 with the plate numbers. In some cases you may get more but it also depends on how long you want take to sell them. Even at the prices mentioned I think they will still take quite a white to sell.
If you wanted to sell the roll fast their are a few ways to do it. You could consign it to one of the better stamp auction firms, they typically charge a 20% commission, and of course you have to wait for the end of the auction. You could also list it yourself on an online auction site, or sell it outright to a stamp dealer. Keep in mind selling the whole roll at once although a lot faster will not net you as much, for the same reason stated above as the dealer (pretty much the only buyers) has a large initial cost and a very slow pay back period. (I still have some imperf error rolls after more than 3 years). I would expect the roll to sell for approximately 25-33% of the estimated retail value, in this case from about $600-$1000.
Robert, I hope this helps, and good luck in whatever you decide, great find.
If you have any further questions just let me know.

Thanks again for the question,
