It's a lot of junk rare and too much junk rare to really compensate for the good stuff if you sell it all bulk. You have good cards among them (use DM Wiki for help). Things like Dogiragon Buster, Bolshack Dogiragon, Miradante Twelve are popular and go for a some bucks each. But those cards all have reprints and for the people who'd want them they'd rather purchase them single then buy them as part of a smaller lot.
Sadly there is too few things that I'm personally interested in order to this to buy this as a whole. I would only want the DM-13 Dolgeza if it's in good condition and the DMR-20 Daddy Pine.
