I can do some checking/digging. I have some factory inventory sheets and production numbers from the seattle factory. I may be able to tell you when it was made. As to value, it really depends on how bad you want one. I had a MKI that I paid $550.00 for w/ 3 original mags and later sold it for $475 and kept 2 of the mags. considering the mags go for $40-60 I was happy. Send me an email so I can email you direct w/ the info that I find.
