Well, if fewer than 500 were made, that's a good thing as far as rarity goes. I suppose to a collector looking for a Solida 35 in clean condition, your camera would have some value; I am not a serious camera collector, but my thinking is that if it is one of fewer than 500, that would make it a very difficult camera to acquire--it's NOT like say a Kodak Retina model of which there were 20,000 made. Value and price are tricky things...the right buyer with the right level of desire could drive the price to a pretty penny, I would think. Let's put it this way: I think the camera "might" be worth at least $500 to the "right" collector. Perhaps even more. I would definitely not sell it "locally" without first having listed it on a big site like e-Bay, or without having done more research on actual sales of the Solida in recent auctions.
