UD Website and Hologram Question

I have found some buy back auto's on ebay that I was interested in. they have the UD hologram on the back. However when I go to the UD website they arent recognized by the search function.
Anyone know how to track down whether these are legit cards??? Beckett doesnt always have all Buybacks listed in the catalog. They are a little better on line.
However, I do like that UD has front and backs available of the cards to look at on line.
