I have so many unopened boxes from my days working for PES, that I got tired of opening every box and then trying to find stuff later. I am not very organized with my magic cards.
I just thought it might be a bit profitable.
I have only sold anything to a friend with a store. I have also rarely bought any magic cards over the years, other than the dual lands about $40 total?
Ah, maybe that's a common part of the whole "individual players sitting on unopened boxes" thing. Just that it's convenient for some people and they hope to perhaps make some money off it. And then the vocal minority that are actually taking it more seriously are just what people like me see more of. Makes sense.
From what I've seen, if you have boxes that have been sitting sealed for several years, they've probably gone up a fair bit. And of course, you might want to sit on them even longer and hope that they go up even more, although at some point they hit diminishing returns. But for specifics, I certainly wouldn't be the person to ask. I don't think we have anyone here these days who is
really versed in the whole "MTG Finance" thing.
My booster box purchases have all been pretty much sunk costs. I buy a couple of boxes of new sets as they hit shelves. Preordered two boxes MM17 before the spoilers drove the prices up, so I'm getting a reasonable deal on those. I've been a bit torns with regard to some of the not-quite-old-not-quite-new sets that I own little of right now, whether it makes more sense for me to just buy a box (more expensive, but it can be fun in a way and it provides a nice selection of cards) or to just focus on singles (much cheaper per card, but tedious and the investment to buy complete playsets of stuff can be a bit daunting). I'm not hurting on the more truly recent stuff, but I was pretty much stagnant as far as collecting during my college years, and a lot of that stuff has really gone up in the meantime. I would have loved to have been buying a couple of booster boxes and fat packs and such back when sets like
Zendikar were current, but I couldn't afford it back then. I've shored some of the collection deficiencies up. Last year I know I bought boxes of
Cold Snap (ran across a good deal and previously owned a total of like 7 actual cards from the set in my entire collection) and
Future Sight (it was a good deal at the time for a box of the set, and the price has only gone up, plus I love
Future Sight and my pulls from that box were excellent). I think the year before last I picked up booster boxes of all three sets in Innistrad Block. So yeah, from a financial standpoint, I'm more of a sucker when it comes to this stuff.
