Card Identification Forum

While sorting through my collection, I stumbled upon a few rookies in this set - #161 Jeremy Childs and #195 Tony Fiammetta. Per the current set listing, the rookies are all #d to 999, but mine do not have a serial number on the back of them as the ones in the gallery do. The only non-numbered parallel in this set is the "retail gold" and there is not trace of gold coloring anywhere on these cards nor does it look comparatively like any of the pictures in the gallery. Are my cards missing a serial number or is there a non-numbered version of these rookies that should be listed with the main set? 
 

Any help would be appreciated! Thanks everyone!! 

Out of curiosity, do your cards have a gold front to them? Sometimes a scan might not pick that up. If they do have a gold front to them, then they are more than likely the retail version.

That's what I thought until I saw this

2009 Donruss Rookies & Stars - [Base] - Gold #161 - Jeremy Childs (comc.com)

That's where my mind wandered as well as a possibility, but as you can see in the picture above the gold is pretty visibly a different color and what I have appears to be the "normal" background. 

The number should be on the bottom left corner of the card. I wonder if this was an error with no stamp instead.
