>>54688555>>54688444what this anon said, ideally what you'd do is get the chase cards from each of these sets and then look at auctions for them, find ones that are good quality and reasonably priced, buy a lot of those, mass a bunch (grading isnt worth doing in small numbers), send in all the ones that you think could be 9-10s, and flip the rest on ebay/tcgplayer. Then once the graded cards come in you can flip those for a much higher premium assuming they're good grades (9 or higher, preferably a 10).
Your other alternative is to buy a case or two of every single product as they come out that are worth it (ETBs, UPCs, Booster Boxes, Booster Bundles) and holding them for 2+ years to flip for a premium. This makes you a lot less money over time assuming you can actually turn profits flipping your graded cards, but is also a much lazier way of making money and is "guaranteed" (there is not a single booster box for pokemon that hasn't gone up in value over years-long scale)
