Oh man, those boxes are pretty awesome.
In general I think most boxes can be made to look decent when put into a protector and on a shelf. The key to that being true is that you would need the spine to look decent enough, which might not be the case on those one.
In my opinion any box is better than no box. But based on those ones, once I found upgrades I prolly would just give them to a friend that can use them, since I find it hard to sell horrible condition boxes.
I wish I knew were I packed away 2 NES boxes I picked up a few years back in a large manual lot. They are missing a huge corner of each of the boxes. Basically looks like a dog took a bite out of them.
