Sports card conventions in 2024 - advice needed.
I returned to the hobby almost a year ago after being away for for over two decades. My buddy who lives in Oregon is also back in and we want to attend a really good Sportscard convention somewhere need Southern California/ San Diego/ Los Angeles County. I have gone to 4 shows since I returned to the hobby and three of them had pretty much just recent cards. In one show I could not find one PSA 8/9 vintage card in the entire show. My buddy and I collect cards that are pre 1981 and we are looking for a show that has ample PSA 8-9 hall of famers.
Since he will be travelling hundreds of miles I want to make sure he's not wasting his time going to a convention that has less than 10 dealers with good vintage material. Does anyone know of a 2-3 day convention that has ample dealers selling vintage material?
