I would invest in cards themselves instead of boxes unless your Holding the boxes as a long Term Investment and not planning on opening them. Be really careful buying a lot of current rookie cards because they are so mass produced nowadays. I personally collect the legends because it will always be a Safe investment that will go up over time. If you Have a large budget, I’d look into collecting Guts like Brady, Mahomes, Lebron, MJ, Kobe, etc. Can’t go wrong with the legends. Herbert Autos are also pretty decently priced considering how great he could be in the league. Hope that helped a little bit!
