I have 2 of these. One is printed upside down??? I dont see anyone else listing one like this. 

Sounds like a printing error.  They probably fed the sheet through the printer the wrong way when they printed one side.  Printing errors are not listed in the dB as separate cards/variations.  Some people collect them, some don't.  

The cards from the factory sets were printed differently than those that came from a wax box. As such it makes them look like they are upside down. No value difference between the 2.

The backs of the cards in the factory sets are oriented differently than cards taken from wax packs, giving the appearance that one version or the other is upside down when sorting from the card backs. There are no premiums or discounts for either version.

Probably a user comment or release note would be a good idea. With so many collected cards, any notation would help clarification.
