Robert- do not know that the S&W is a highly sought after collector's gun, but yes, there is some interest in any of the older S&Ws. However- for a collector's piece- condition, condition, condition. And yours DOES show signs of honest wear.
FWIW, I bought one for my stepmom after my dad passed away in '95. She still has it. Stay away from super hot loads, and it should do fine. Nice piece.
