Yeah man, that sounds like a nice deal even if it was just CIB. But, sealed is an even better deal. Congrats on that find, was this the one?

I'm in a hard spot with my 7800 collecting because I have almost all of the carts and instructions so it's hard to find people selling boxes only. I usually have to re-buy the game CIB and then resell the cart and instructions. I currently have 26 CIB 7800 games but not all individual titles, I have both versions of Ballblazer CIB and both Realsports Baseball's CIB so I really only have 24 different titles.
I actually made my Scrapyard Dog CIB by getting a box only from one of Chris Leach's sale threads, I think it was around 4 to 5 bucks shipped. It's really hard to find the boxes in really nice shape, they always seem to have some crushing.
Scrapyard Dog is only rated a 3 but it's still pretty hard to find, just like Midnight Mutants....that one is a 3 too but not only is it hard to find but popular and demands a premium on ebay. I think a CIB one sold recently for just over 40 bucks. These two games are the same rarity as Super Huey and they are new and sealed all over the place....I personally have a bunch of them new and sealed along with a good amount of Fight Night's.
I don't think the 2600 and 7800 AA rarity guide are comparable. Scrapyard Dog is a perfect example, it's only a rarity 3 but doesn't show up that often. However, 2600 rarity 3's are all over the place. Anyway, back to your find...here is the only one on ebay at all and it's sealed for $47 or best offer:

- Rarity 3 but only one on ebay? I think the rarity is off on this one.
Enjoy the game bro, I hope it arrives in nice shape without any creases or crushing.
