Could it have been re-submitted and re-slabbed? Maybe the plastic had gotten cracked? Maybe they wanted the "Eagle Eye Photoseal" instead of the CAC? From my vast 3 minutes of research, everyone seems to choose Eagle Eye over CAC...
I think (not sure) but the one with PS sticker is an older style NGC label than the one with the CAC sticker. I have never come across this situation before. Is there a way to verify the authenticity of each slab?
No chance of that. The CAC slab is the new one. Your initial impression is the most logical though, someone had it reholdered or it became cracked out and resubmitted at some point and went to CAC this time.
The question should be, is where did you come to have both of these items ? Are they in your possession or are they photo captures from God knows where? Need a bit more info if you don't mind. From my observation of these blurry photos, I do see that each coin is one in the same, my opinion of course
I had to screen shot and reformat the pics several times before they would load on this site. The CAC slab is currently for sale at a major auction site and the EEPS slab is a past sales photo at a major coin dealer. (not sure if I'm allowed to post the names of the sites on this forum - willing to pm the info). Question - other than a damaged slab, why would one "reholder" a slab? I was under the impression that older slabs are more desirable by some collectors.
In this case the older slab isn't that old. And why reholder? Possibly because the slab was scuffed, or chipped, possibly they just wanted the newer edgeview holder.
Wouldn't a crack-out submission for a new grade have a different serial number? My guess is maybe something happened to the old holder or someone just wanted to have a new edge-view holder and submitted it for a re-holder.
I would say this is a reholder. I am under the impression that you retain the certificate number at NGC and PCGS when you reholder.
