So I've been holding on to what I thought was a very modest collection, spanning from basketball, football, baseball and hockey. After doing my die diligence, turns out I own hundreds of Junk Wax Era rubbish. I probably have 20-30 cards that will gete $5-$10 a pop. Needless to say, the 12 year old in me that saved all these over the years and thought he was sitting on a treasure trove, was incredibly disappointed. But! I think I not only want to hold on to my PC, but build on it. I'm pushing 40 and I recently got sober, so I kinda need a hobby. I guess what I'm asking is, how do I go about this hobby? Buy some top loaders and upgrade the cards I have? But proper storage for my PC, and just shop eBay and whatnot? I'm simply asking for guidance and any tips on how to dig into this hobby PROPERLY. I appreciate any and all advice.
