One thing I've never been clear on is on cards are serial numbered. Do they feed entire sheets through machines, one card at a time? I have no idea. Which brings me to today. I've found a number of oddities in the Masterpieces sets. I've found foil less cards:
In fact I believe I have two sets of these particular foil less cards.
I've found an eli manning/YA Tittle that was printed on the wrong side of the card:
I've seen no other card like this in all of the cases and cards I have manhandled.
I've come across cards that have the incorrect frame for the numbering:
and this Marvin Harrison serial numbered 51/50
But today I ran into something entirely different. Whilst perusing COMC for the 10th time today, I notice a Jonathan Stewart that was listed as being /15. There is no such thing in this set. There's /10/25/50/75/99/150/199 There's also the Silver that are numbered to the Jersey number. I knew this wasn't simply an odd numbering for the silver as the extended Rookies 101-110 were not included in that set. So I just thought it was an error in the listing until I decided to look at the scan of the back:
I grabbed it immediately and paid way too much for it. Now I have no idea how the machine got set to /15. Maybe someone can enlighten me to how this whole thing works.
