Scott 65 With Lateral Margins, Perfs, Color From The Adjoining Stamps. How Would I Grade This?

The big problem with double perforations:
All of these issues were printed by various bank note companies. Over time, they were all eventually bought up by American Banknote Co. So eventually ABNCO found themselves with a lot of other bank note company archives which they did not need. This not only included proofs and essays, but perforating wheels and other metal as well, all of which they sold off as scrap (almost always to stamp dealers). Back in the 1890's double perf varieties were very popular, and there were certainly people ready and willing to help create a supply to fill the demand. This happened with revenues as well. So while there is no doubt that some genuine double perf examples exist, many are likely not.

Hey revcollector,

You spoke of how to check for pressure ridges to help in trying to prove that the perfs are genuine in this thread.

"Help with R84c strange corner perfs".

There is some information on that thread as to how to check and what you should see.

Good luck

Some things never change:

U.S stamp, #234 Columbian, double perf'd, FAKE

It seems that my original question is being answered by members who seem to know the subject quite well. There's quite a lot to learn. Thanks, all!

Just like in Baseball,they are errors. No need to grade them, they have been graded as an error by the perforator.

Well, not quite Stuart, Some of them are actually double perforated in the normal course of production. But their popularity increased their availability when the perforation equipment became available. Telling the true production errors from the later "post production" modified stamps would be probematic at best. Some are true errors, while others are manufactured errors.

Revcollector - and others.
What is your opinion on revenues of modest value on documents, properly tied with ms or hs cancels and displaying extra rows or columns of perfs?
Certainly normal perfed stamps could have been neatly removed and had
bogus perfs added, then replaced.
I am not a revenue specialist but do appreciate and have kept several of the (what I believe to be genuine) extra-perfed stamps, if they have some kind of validity.
Thanks
Bill

If the cancellation is across the extra perfs, one should be able to tell if the cancellation came before or after the perforations were applied.
