For g-u items in general, including balls and bases, I like to get as much info as possible. I use MLB.com gameday and retrosheet.org to give the fuller story of the game situation or at least the game itself if the MLB hologram isn't specific enough to give the actual situation. I'll print out the play-by-play from those sites. Those things add to the enjoyment of the item for me.

Of course I usually have to do this research after I've bought it, if from a team store. However, some stores, if not too busy, will use their Internet to help you get more info before you buy.
