I picked up a Donkey Kong last week that was missing a coin door. I would like to buy a complete Nintendo coin door with mechs. I would also be glad to trade for the coin door in the photos, if anyone is interested.
Nintendo coin doors are hard to come by,especially ones with out dents and straight frames.
That one on eBay looks good for repainting. If you don't need the mechs then you could sell them to get some $$ back.
The main thing to look for is that the frame is straight,if is bent then it is a major hassle to get it to look good.
I lucked out and found one in perfect shape with original finish.
