Fake Printing Errors

Our advice when dealing with errors and misprints is to be very wary of any error that could in theory have been created with an eraser, scissors, or a printer.  That covers a lot of errors.  Today we are specifically looking at fake overprint errors.  Authentic errors are the result of paper being feed through the printer twice.  These errors can also result from foldovers and offsets.

First, let’s look at the fake error.  We received this image over the weekend.  It is a $10 bill with a $20 bill printed on the bottom corner of it.  If this error was authentic it would be extremely rare and valuable.  However, this is a fake and it is easy to spot.  You can apply this bit of information to help spot lots of fake errors.  So, the $10 is likely authentic.  I can’t say for certain without holding it in hand.  However, there is no reason to fake it.  What someone has done is taken a $10 bill and run it through a printer and put the image of a $20 bill on the bottom corner.  Here is the giveaway.  The printing process doesn’t add color to make the $10 bill orange or the $20 bill green.  The paper each note is printed on is that color.  So if this were an authentic error then there would be no color associated with $20 overprint.  It would just be black ink.  Anytime you see color changes in the margin or on the bank note, then you know you are dealing with an error someone printed at home.

Now let’s look at an authentic error.  First off, you can see that there is no color change associated with the margins on the overprinted bank note.  It is simply just black ink.  That is good.  You might also notice that the overprinted image is mirrored.  That is another sign that you are dealing with an authentic error.  The fake error is not mirrored.  The only way it could have been applied would have been from a direct printing which is highly improbable.  The authentic error is like the result of an offset.  It could also be the result of a foldover, but that is less likely.  Either way, it is an authentic error and probably worth around $150 in that condition.
