Season Ticket stock is more difficult to track down in my experience but well worth it when you can find it for an affordable price. I had some good fortune in locking down some lots of tickets in 2020-2022 and one such lot included a handful of LeBron James rookie year fulls.
I also learned that for basketball limiting myself to a search of, say, 2003 for LBJ would not be the most fruitful approach. Basketball seasons span two years and not everyone lists a 2004 ticket that occurs pre-summer months as a rookie even though it very much is.
