Class VI : Distended Hub Doubling

Distended hub doubling is the only class of doubling that shows no separation in the doubling. This can occur because the working hub is softer than the working die and during the hubbing process the images become distorted. The letters are thicker and flatter than on a normal die.

What to look for :

No separation of any images can be seen. The doubling takes the form of extra thickness on the letters, digits or design elements.
