I did some work on the Ray Knight Scar Variations — take a look here:
http://forums.collectors.com/messageview.cfm?catid=11&threadid=831260
Has anyone ever worked out the distribution of the copyright and denotes variations? I just did a quick scan of eBay and found all these different types of cases (sorted by UPC):
wax case (20 boxes/720 packs (36@)) UPC 10700-82500
rack case (72 packs) UPC 10700-82502
wax display case (2 displays/432 packs (216@)) UPC 10700-82504
wax case (10 boxes/360 packs (36@)) UPC 10700-82507
blister case (48 packs) flat red lettered box UPC 10700-82509-20
blister case (48 packs) tall blue lettered box UPC 10700-82510
cello case (12 boxes/288 packs (24@)) UPC 10700-82520
cello case (12 boxes/288 packs (24@)) flat box UPC 10700-82521
cello case (6 shelf extenders/300 packs (50@)) UPC 10700-82522
factory set case (15 sets) UPC 10700-82005 (not sure of this is for the white box or the colorful box)
That’s a lot of different ways to pull cards. I’m curious if there are variations specific to wax vs blister vs cello vs rack.
