I picked this one up a few years ago and forgot that I had it. It’s a series 1974 $1.00. The entire front of the bill is printed in black ink over the green ink on the back of the bill. A nice overprint.
Called a " Wet Ink Transfer" Error . Nice ! Wet ink transfers happen when, in error, a sheet of currency paper does not enter the press, the inked printing plate will contact the impression cylinder. When the next and subsequent sheets enter the press, they receive both the intended printing on the correct side and an impression on the opposite side from the ink left on the cylinder.
I’ve heard the term Wet Ink Transfer before, but prefer to use the term Offset Printing instead. Both mean the same thing. The OP’s note is a full Front-to-Back Offset Printing with bold inking. You’ll find most small-size paper money errors are on notes printed in the 1970s,1980s and 1990s. Super nice note.
When I saw this for sale I couldn’t believe it, especially when I saw the low price. It was one of those moments, you see it, you gotta have it. It’s mine now.
It’s newer but it’s as crisp today as the day it was printed. Not a gold , crease or bent corner anywhere.
Be wary of these "front to back" notes listed on eBay. Many are simply printed on the back with a laser printer. Usually these fakes do not have the sharp/crisp lines of engraving. Inspect them carefully.
I don’t buy or sell anything on eBay. This was purchased from an extremely reputable source but since hear you.
With so much ink transferred onto the back of some notes you would expect there to be counterpart errors, with faint ghosted image on the front of some notes. Do those exist?
The plate is inked but no paper is feed into the press so the ink is transferred to the opposite press. Then paper goes in and they print like this. The ink wears off as more sheets are printed.
Clashed ink plates ? I don’t believe plates are clashing. The intaglio printing process involves feeding the security paper between an engraved, inked plate and an impression cylinder. The cylinder forces the paper against the plate. Here’s a crude diagram to illustrate the process.
They do, but face to back are more common because of the printing process. The back is printed first so the image of the back on both sides is easier to spot by QC than the extra image of the face printed on the already printed back.
