I know you asked ABF specifically, but I thought I'd add my two cents. Just from looking around online, I regret to say this doesn't appear to be that rare a game. From what I'm seeing, even on eBay where items tend to be overpriced a complete-in-box set is going for $25-35. Further, there are a decent number of listings, which tells me at least that demand isn't as high as supply, and perhaps that it's pretty common. This looks like a typical PC "compilation" box at that, which might explain it being rather low priced. Compilations in general tend to be missing a lot of the pack-in goodies the original releases had, and PC compilations are rather noteworthy for missing content that was on the original disks. They aren't going to be as sought after as the "originals".
If you're looking to flip it, you might try as high as $40 if you're willing to wait a while, but if you want a quick sale, those eBay prices are probably your best bet.
And, while I was looking, this one caught my eye:

That's not a good sign I'm afraid. Let's just say this is no IBM King's Quest.
http://www.vintage-sierra.net/kq/kqv1.php Now THAT'S a version of a game that goes for a King's ransom (often clearing over $600, and likely higher at this point, since as of now there are NO copies of that particular version of the game on eBay or Amazon).
You might own some games that will sell for a lot more than that. Earthbound has been going down in price, but it still easily clears $100 and can get over $200, and that's for the cart alone. Conker's Bad Fur Day can also go for a pretty penny. If you somehow have a copy of Shantae for Gameboy Color, you're looking at a small fortune, often selling for over $300. Heck, the special component cables for the Gamecube (the ones that let you play in 480p) can sell for over $200 by themselves.
I'm not saying you should clear out your collection of old games if you're fond of them, but everything I just listed has a MUCH cheaper modern alternative if playing it on "original hardware" doesn't matter to you. You can play Gamecube games with component on a Wii, for example. Both Earthbound and Shantae can be bought as virtual console games on the 3DS (Earthbound is also on the Wii U, but I think it's more likely you own a 3DS). Conker's Bad Fur Day can be bought in a collection for the XBox One, and that's the N64 version, not the "Reloaded" version. Depending on what you already own and what you want to sell, you could make a tidy profit, and spend a pittance of that on replacing the game you just sold with a FAR cheaper digital alternative. It becomes less of a "sure thing" if you don't have any of those more modern consoles, because then you'd have to factor in the price of the console. Conker's Bad Fur Day sells decently, but not nearly enough to justify buying an XBox One for the emulated version as a replacement.
Well, these are some things to consider, but as for your box set... Well, heck, consider holding on to it and seeing if the prices go up in a year. If they do, you've got a potential investment. If not, it's probably not going to get any higher as time goes on.
