I think there may be an extra variants here.
First, some barcode issues…
- 1H should be 75960620239300181 (not 171)
- 1I should be 75960620239300119 (not 181)
- 2E should be 75960620239300271
(I own all of these).
Now that leaves 1J. The barcode assigned to 1J is the barcode that should be assigned to 1I. And I’m not finding a Mico cover to Exodus #1 (there are several Mico covers to Spider-Man 2099 Exodus- Alpha #1, but none that I can find to the regular Exodus #1). So I think 1J might be extra.
Also, that leaves 2H. The barcode to 2H matches what is indexed as 2E. So I think 2E and 2H might be the same.
