I'm glad you mentioned in your question "machine doubling."

A subject I've come to the conclusion that is what it is. On a normal doubled die with the raised devices, the hub doubling widens/thickens the devices. On machine doubled examples the devices are reduced is width/height but often show parts of the full devices. These are normal sized, but reduce because of the Machine Doubling.

On incuse devices like the VDB, EPU on Shield cents, the "State Parks" quarters on the outside devices, when Machine Doubling happens on the incuse devices like these, increases the sizes of the devices. On hub doubled examples of incuse devices, these are actually reduced. Kind of confusing, but realizing what the difference is helps us to under stand this.
On a Shield cent this is what a doubled die would look like:

Note how the incuse devices are enlarged as compared with a normal die?
But on the incuse devices of the EPU, the devices are reduced with hub doubling:


Machine Doubling on raised devices reduce the overall shape of the devices:





On incuse devices, the Machine Doubling looks like your initals "VDB" on the cent. They are enlarged. (Wish I had more images of the quarters examples.)
But I hope this helps?

Can I add your image of the VDB to my image files?

Coop,

You can add the image to your files if you like.

Sudz,

I'll try and get a close up of the LB on reverse when I get a chance.

Thanks for the info all!
