I have also seen plenty of examples where I believe prices in the Blue Book are too low. However, if we use some logic, if another M56 in .22 short came up for sale, why should it sell for anywhere close to $3580? This particular auction came down to only two bidders once it hit $2000 and they slugged it out all the way to the end. So, for one guy, the itch got scratched; for the other guy not. So we know there remains one guy out there who is likely still willing to pay over $3500 for one of these, but where is the other guy to drive it up that far? From what I can tell, if another one came along it is more likely the bidding would top out closer to $2000.
