Quoted from dung:Interesting, but tbh not really seeing the *collectibility* a few people might want something specific to a game they own, but there are dozens of blueprints for any given game. Designers and various people have been on here selling prints of pf art, proto playfields, proofs etc over the years and often times they sit so unless these are fairly cheap I can't see their being a huge market. As for their being a COA, its probably as necessary as the cheap printer coa my avatar le came with, ie not worth the paper its printed on.
I think the value is completely dependent on what the drawing is. For example, I have a Genco bball game and during the repair process I downloaded the patent application for the manikin. It contains detailed, exploded drawings of the mechanism. You can immediately recognize it as the bball player in the game. An original drawing with notes on it would be something I would pay a whole lot more than $20 for and I suspect others would do the same, driving the price into three figures. I would buy it, not as a collectible per se, but as an interesting piece of art. On the other hand, a drawing of the start button? Not interested.
