These things just don't seem to show up like they used to. Either the BEP printing technology has gotten better or the inspection quality control has gotten better. Probably a little bit of both.
Always a nice error to add to a collection. Congrats on "rediscovering" and sharing yours!

Nice. What would be the difference between an offset printing error and a wet ink transfer? John1  |

One of the tell-tale signs that this is a legit offset transfer error is the checkered pattern you can see especially in the area of the Great Seal.
The reason it is called an offset transfer error is because it occurs in a manner similar to how offset printing is done. Offset lithography involves the image from the plate being transferred to a roller and then the paper contacts the roller and picks up the ink from the roller.
This error is caused by a sheet misfeeding or folding so that the plate comes in contact with the bed the sheet rests on. When the next sheet feeds through, the image on the bed is picked up on the bottom of the next sheets until the ink on the bed is gone.
That bed is made of woven cloth. The pattern you see is the weave of the cloth. Fakers cannot duplicate that pattern (or at least they don't know that they should).
I disagree with Steve that an offset transfer error and a wet ink transfer are the same thing. A wet ink transfer is caused by sheets being stacked while the ink is still wet. It has nothing to do with a misfed sheet and the image transferring from the bed like an offset transfer error.

I understand and agree with your explanation Jim, thank you.
In my defense, it's right out of Fred Bart's Paper Money Error Guide.

I just asked my pressman again, the way he explain to me is offset transfer is normally due to the weight of the paper/stock laying on top of each sheets coming off the press, and the ink hasn't completely dry up either from the heating or powder wasn't set properly. This is usually caught by the QC before sending off to the cutter operator.
Wet ink transfer are usually due to the pressure of the cutter making the transfer when one or both side is not fully dry before cutting.
I wish at time that the cutter can test cut a small lift before cutting an entire skid, so I don't have to tell the pressman the bad news.

My understanding is that an "Offset Printing" or "Offset Transfer" error happens when an inked plate makes contact with the bed, leading to no sheet being fed to the press to accept the intended ink. As a result, when the next sheet passes through the press, the area impressed onto the impression cylinder is then pressed onto the opposite side of the note. Here is my one and only example, for which I paid a significant premium due to extreme it is:  |
