I call this:
Grafternoon Delight - feeling like you commited a crime, because you won a card at such a low price only because of the early, extremely-low-traffic time of day the auction ended.
It wasn't too long ago when I finally grabbed one of these awesome 1964
Koufax cards (showing him in action before 'in action' was a thing) in PSA 8 OC shape. Well, I was happy to get another one for a lot less than what the last few (with similar centering) went for, probably because the auction ended early in the day when no one was watching...
