Stamp Errors: Invert Errors and Head to Tail Error

Invert Error 

The printing of stamps in the earlier time was done through plates with design engraved on them. In order to print a second colour, a second plate was needed, making the printing process slower and more expensive. When the sheet is not correctly placed, for example if it is paced upside down when going through the second print, the design produces stamps with Invert Errors.

Inverted Jenny

Inverted Jenny is one of the most famous error in American stamps; a mistake that is now worth millions. The Inverted Jenny is also known as an Upside Down Jenny or Jenny Invert. It is a 24 cent United States postage stamp first issued on May 10, 1918, in which the image of the Curtiss JN-4 airplane in the center of the design is printed upside-down.


Tête-bêche or Head to Tail Error

The individual cells that print each stamp in a sheet are called as cliche or subjects of the plate. These are assembled to print the stamps on paper, creating a grid/sheet of stamps. If the cliches are not aligned correctly, the stamps are printed upside down relative to other stamps. Tête-bêche can also be intentional too.
