Re: What is my mod. 57 worth
According to standard catalog of S&W, N748xxx is 1980, year could vary as pistols were not shipped in serial number order. S&W changed to n prefix serial number in 1969, switched to 57-1 in 1982. As new in box 650, exc 575, vg 400, good 325, fair 265, although I have seen some realize higher prices at auction. Presentation case value is in addition to above prices.
