I can't get the picture to come up. It keeps coming up a lever action rifle for me. But, it doesn't matter what the serial is- the Y Model 12s started at serial number 2,000,000. So, if the serial number is less than that, it shouldn't be a Y Model. And a Y Model will have a Y stamped before the serial number. As far as price goes, I would think it would depend on the area of the country, obviously. I nice vented Y Model 12 around here would run in the $1000.00 range. I am talking really nice. A vented Model 12 stamped SKEET should go for a lot more than that like was mentioned. And eightbore, if you saw a mint Y Model skeet for $650.00- you should have bought it. It is probably worth twice that much. The more the Model 12s keep dwindling, the more the value will go up. Now, even the nice Y Models are getting scarce. People are starting to treat them like a regular one. So, the value on them will continue to rise too. Good luck.
