Hi Geremy,

Thank you for contacting Mearto with your appraisal inquiry.
Misprinted bills such as this one you have - and the $10 bill in the other appraisal you've submitted - are caused when a sheet fails to enter the printing press and the inked plates transfer their image to the impression cylinder. The next 6 or 7 sheets will receive the impression from the cylinder while the other side of the note is being printed. The result is an offset printing in reverse on the already printed side. These bills usually bring between $200-300 at auction each.
Based on the photos and information provided, and subject to examination, this is:

A mis-printed United States $5 bill
1988, serial number L33368962G
imprint of front transferred to the back of the bill
2 by 6 inches
CONDITION: not graded
$200-300*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, and thank you again for using Mearto.
