They aren't the traditional "Error Card" like everybody says that they are.  A true error card is when the factory purposely prints a card with the wrong information or picture or whatever.  An example of this would be the Griffin/Rua mat relic from R1 that has the wrong event and date on it, or the Wilson Gouveia Ultimate Gear that has his name spelled wrong.

 

In the traditional trading card world, a product is printed and released over a looong period of time.  When there is an "error card," it is often caught and corrected.  That means that the ones with the errors on them are cool and more rare.  It follows, that they are more valuable.  In Topps UFC Round 1, the true errors are equally as common as the non-errors and therefore not really noteworthy.

 

In general, collectors consider misprinted cards to not be "error cards," and do not give them much attention.  They are instead seen as f**ked up cards.  You could probably send them back to topps and ask for replacements.  That wouldn't be worth it, as they are base cards and are cool as a novelty.
