There are several variations of the 657 mountain gun. these are indicated by a dash (-) and a number after the model #. The general rule is the lower the number after the dash the earlier the manufacturing date and the more valuable the gun. unfortunately it is not that easy. There many other factors that determine value and each gun needs to be appraised individually. To be very general, Model 657's values range from $500 to $1000. Mountain guns usually bring a premium.
well, it depends... the 657 sells new around 800 i beleive.. most gun dealers like to give you about 50-60% of the new value. even in 90% condition. but if you find the right person you can probably bring around 500.00 i paid 500 for mine along with 900 handloads,a scope and mount, and hoslter..
