Honestly, I’m not sure how to price this. In general, when you want to know what something is worth, a typical price-checking strategy is to find out how much it would cost to go buy one somewhere else. But I don’t think I would be able to go out right now and find another autographed original MM prototype for sale, at any price.

Actually (and I don’t really know), it seems possible that there has never been another autographed MM prototype like this posted for public sale, ever. I bought it from TreasureCove decades ago, just by word of mouth, and I think a lot of games like this are just sold by word of mouth, and never posted for sale to the public.

UPDATE: Current best offer starts with a "2", so I won't be considering any more offers that start with a "1", sorry. Thanks for all the interest!

Description:
This Medieval Madness is one of the 15 original prototypes. It was given to Greg Freres, the game’s art designer, for his private home collection. The game is autographed and has a prototype playfield with artwork different than the production version.

The circuit boards under the playfield are red. Software 0.99 is installed. In various places around the game, there are extra holes where the design was adjusted. Some ball guides were welded by hand. The manual is autographed by the game’s software designer, Lyman Sheats. The coin door includes an informative plaque about Prototype #13.

Let me know if you have any questions.

Note: THIS IS NOT A SCAM! If you want proof that the game is real and in my possession, let me know, and we can do a facetime call or something like that. I assure you that this game is real, and I have it.
