The S&W model 64 is a stainless-steel version of the model 10, a fixed-sight service style revolver made on the K frame. It was introduced on Sept 1, 1970 at s/n D224001.
Originally it was made with either 4" light tapered barrel with square butt, or 2" barrel with round butt. Later a 3" barrel version and heavy-barrel 4" version were offered as well. In all its variations the model 64 was a very well made, high quality revolver.
Some were made in .357 Magnum for the Oklahoma Highway Patrol and marked model 64-1, this version was then renamed the model 65. Both the 64 and 65 were very popular police sidearms in the '70s and '80s.
S/N D490XXX would date to 1972-1973, most likely early 1973.
Can't say your pawn shop estimate is wrong but it sure is a wide range. You might do a search at the gunsamerica, gunbroker and gunsinternational sites where you'll see photos and prices. That way you can see what asking prices are for revolvers in condition similar to yours.
