Edited-Meant to say that they are printed in 2 differant locations.Wonder if thats because series 1 and 2?
All the additions have been added with the exception of 1992 and 1993 Upper Deck Golds, only because they are widely recognized parallels to the base set. This is quickly becoming a pretty comprehensive list!
In regards to the 1991 Upper Deck hologram variations:
Low series have different holograms that hi series and final edition. This is why your Butlers varied.
However, Upper Deck used a specific hologram for it's 1990 cards that has a blurry cluster of baseballs. Flip over any 1990 UD card to notice this. Upper Deck printed some of it's 1991s with this old hologram type. (Affects low #s only AFAIK)
Upper Deck Hockey 1990-91 Hi series had a specific type of hologram as well. In it you can clearly see the "90" ( and sometimes hockey sticks) floating around in the hologram image. For whatever reason, Upper Deck printed some of it's 1991 baseball with this holo type. (Affects low #s only AFAIK)
1991 Upper Deck baseball is commonly found with it's intended 1991 type. In this hologram you can see the year "91" (in small type) repeated.
1991 Upper Deck low and hi cards can be found with the Hologram type used in it's Hi# basketball and Football cards. This hologram has an Upper Deck logo/diamond pattern to it.
This is a variation I have been aware of for years but only started to recognize once I was sorting a large quantity of 1991s. When you see these examples together, they seems a little less trivial and instead tell an interesting story of the running changes to their product which can essentially date a specific version of your player's card. A card using the 1990 hologram would likely be an earlier printing than say the card with the 1991-92 NBA holo. Once you have seen each type, you will be immediately aware of their differences.
Oh and the copyrights are placed on two different locations based on low and hi series. Along back photo for hi and under MLB logos for low.
