JDB, there are people here that are 1000x more knowledgeable about collecting S&W revolvers than I am. I would guess that pristine examples of pre-war Registered Magnums and guns like .38-.44 Heavy Duty guns are some of the most sought after guns by S&W collectors. There is absolutely nothing wrong with collecting pristine examples of guns like yours. My point is/was, there were an awful lot of Model-19s manufactured; they aren't "rare." The same can be said of most of the guns we all love to acquire to shoot, admire, or as investments. There are people who collect Model 10s, which I guess are the most common gun S&W made. I once saw "collector" described as someone who has more than one example of a given item. I have 3 Model 19s, and "several" Model 10s/M&Ps, so I guess that makes me a collector. I shoot all of them, though.
I certainly wasn't denigrating your gun. Personally, the Model 19 is about tied with the Models 15 and 17 as my favorite S&Ws. Those pinned and recessed guns, in my estimation, represent just about the finest examples of production revolvers in the mid-20th century. They aren't "rare collectables" (even though they definitely are collectable) just because so many were produced.
