Just got another 23, there's some difference esp the shoes, the XI doesn't crease as easy as my 1st one, and the patterns on the other 2 shoes are more detailed, esp the soles you can see the grooves more deep than the other ones, and the paint are slightly different, maybe it's hand mixed & hand painted? One has darker red than the other pair, and the X one is whiter than the other pair.
The 2nd MJ doesn't have the leg problem, jersey are pretty good but i notice some sticky icky on the front C which i had problem removing, then there's a small patch of white (not very noticeable) on the right side of the chest.
I think the QC varies depending on the batch. I got the 2nd set $25 more expensive because i pre-ordered & paid some deposit while i managed to get my 1st set cheaper.
The color & paint job on the ball also differs, the ball & hand magnet differ with different figures, some has +ve on the ball while some has -ve on the ball so Make sure you don't mix them up if you have multiple MJ.
The 1st MVP trophy had it's sticker slightly off few degrees, while the 2nd set was pretty perfect.
I got 2 because i wanted 1 in Warm Up and the other in action pose, the Black still cost too much. My initial plans was to sell off the hands, jerseys, extra shoes & hands but now i think i will only let go the extra hands minus the magnet hands & 2 pairs of AJ, and probably the box, not sure whether it's a smart idea or should i just keep everything? I don't really need same pair of AJs.
