2005 Upper Deck Baseball Heroes Baseball Forum

Came across these sets of cards on eBay and have been unable to find anything about non-serial numbered versions of these colored parallel sets. 
 

Seller has multiple Emerald and Red sets of different players that are not serial numbered. They stated these were “produced by Upper Deck BEFORE the ones with serial numbers” and sent to him from Upper Deck back in 2005. I can “check with Upper Deck directly” if I have any doubts. “They are authentic cards.”

Curious if anyone has knowledge of this non-serial numbered version and if this needs to be added to the site?

I asked about them previously in this thread:

Personally, I'm leaning toward "counterfeit"

I looked but didn’t see that forum. 
 

The Seller has responded to my questions as I posted his responses. I’m not sure how to “check with UD if I have doubts”.  I also asked about the backs and if they had “Sample” or something on them. He said they were identical backs and were not sample issues. He stated “they anre authentic cards”.

I'm not sure if I would call them "counterfeit"    More like back doored cards.   Those are not allowed here   

"produced by Upper Deck BEFORE the ones with serial numbers" would suggest they were some sort of test print that was supposed to be destroyed/discarded afterwards. Doesn't seem like something that was supposed to be put out for collection.

Be careful. I'm slightly bitter about receiving 4 Upper Deck Cards "NON-SERIALLY NUMBERED" from eBay.  I guess I should have read the description. This guy's whole store is these Emerald Upper Deck Baseball Heroes cards that are NON-SERIALLY NUMBERED. It seems like a scam. Does anyone have any more information? 

I've been looking at both the Red and Emerald Mike Schmidt sets on Ebay (georeps_42) for some time now. So, I decided to pull the trigger and purchase both sets (43 + S/H). They came in the other day and after looking at them, I do believe they are real cards. They are the correct thickness, pretty well cut and centered and the hologram is the same as the base beige version for that year. With that, I also believe they were "removed" from the production line before the stamping of the serial numbers occurred. Either Upper Deck was preforming a quality test and pull a few sets out of production, or they were stolen. Either way, they made it to the market. test

The seller of these cards can't have many of them available. So, in my opinion that makes them somewhat rare.

As a collector of Schmidt cards, I will add them to my personal collection. One day I hope to see a Blue non serial numbered set out there.
