A list of errors

[thrawn]

here is a list of all the possible different mistakes that can occur to paper money, there is not alot of point in knowing all this (most incorect notes will be valuable) other than to impress your ( - - blocked - - )! I will post a similar one for coins

Board Break - A result of a partially broken impression cylinder. Sometimes extreme pressure from strikes or passes can cause fatigued areas and cause the cylinder to either compress or crack resulting in this type of error.

Double Denomination - The King of Paper Money Errors! A face printed with one denomination and the back of the note printed with another denomination. VERY RARE and fascinating. This error commands a GIANT PREMIUM!

Faulty Alignments - Improper alignment of printed design. Very easily identified. One side of the note is usually centered very well as compared to the other. Dramatic errors of this type are few and far between.

Ink Errors - Smears, smudges, spills, overinked plates, underinked plates, etc.. One of the most common errors found. Can range from a small fine line to a obliteration of the design. Many of these errors have been faked, but they are distinguishable mostly by "feel".

Inverted Backs - When the back of the note appears to be printed upside down! Rarely noticed ... upon independent examination of each side, the note appears normal. Feeding in sheets upside down after the first printing by BEP operators causes this.

Obstructions - When a foreign object somehow comes between the paper and the printing plate during production, often leaving a blank area on one isolated portion of the note. Sometimes collectors obtain the obstruction as well, making the find even most lucrative!

Offset Printings - Impressive errors that look like one side of the note "bled" through the other side. The offset or Wet Ink Transfer places a mirror image on the wrong side of the note. Often called "blanket impressions" Some printing errors are more distinguishable that others.

Overprints (Inverted, Misaligned and Missing) - Bizarre and Unusual looking appearance of the overprint (Seal and Serial Numbers) This happens to be an "inverted overprint", but at times the overprint is missing altogether or misaligned.

( - - blocked - - ) Serial Numbers - Serial Numbers sometimes malfunction due to mechanical failure. The failure for one serial number digit to rotate will cause a ( - - blocked - - ) of the two printed numbers on the face of the note. Sometimes tough to spot.

Stuck Digits - Digit on serial number occasionally gets stuck and does not fully rotate. Much like the odometer on your car between miles being recorded. Another error mostly due to mechanical failure.

Cutting Errors - Miscuts arising during the terminal stage of production due to blades, paper jams, etc... Often these errors have been "faked" by those looking to "create" an error and sell on the open market for a premium.

Gutter Folds - Characterized by a blank, unprinted white channel interrupting the face, back or overprint. Often caused by a deep wrinkle in the paper as it received an image. Relatively common ... and often, multiple folds are present.

Multiple Errors - Sometimes multiple errors can appear on a note. Combining the probability of the specific type of errors will determine its rarity. These notes are very desirable by collectors often baffling the novice.

I was not knowing about any of such error, I just use to take it as a simple printing from printer, Man its gonna take the hell out of the printing personels.
