The last several Dig Dug's I have seen at auction went for around that price. Funny enough, I believe that is the same Dig Dug I saw at auction a few years ago based upon the water damage, nails in the t-molding, painted sides and back, and hole in the side (the pics shows all of this). I believe it sold for $350-$400 at that auction (I considered it, but passed). BTW, it played fine back then and was original inside, but who knows what has changed since then.
