What the heck is a reverse proof?

I've never even heard that term until the mint announced reverse proofs in the 20th anniversary sets. Has anyone seen one, or have a photo, or can anyone explain how they are different from a regular proof?

<< <i>I wonder how they do that. It would be hard to polish only the devices on the die >>
You polish the whole die, put 'protection over the devices and lettering, then sandblast the dieface.
<< <i> do they polish the portion of the planchet which has the device? >>
No. If you tried to do that then you would have to VERY carefully position every planchet before striking.
