It seems like this is a "real" error, regarding the word "poker" missing.

My question is I read an Ebay listing that states:

"Even has the Hologram on one side that's pretty UN common too!"

What exactly does this mean? When I think of a hologram, I think of the little silvery thing that prevents counterfeiting..like Upper Deck used to have on its baseball cards.

Is there one of these on the Mirage Chips, or does "hologram" refer to something else?

Thank you for any info..
