The Model 60 was the first stainless steel revolver that S&W made. At the time, super rare in high demand, so I couldn't find one at any price. My first stainless purchase was in 1973 and it was a Model 67.
Because of this, the Model 60 has sentimental value to a lot of us. We can find and afford the pistols that we couldn't back "in the day". At least that's where I found myself in the mid-80's when I finally got my first Model 60.
I've owned several over the years. Every one of them was a spur of the moment purchase that involved the money I had in my pocket at the time and the pistol that the seller had in his hand. It's a revolver that you will have no trouble selling, ever. The trick is to go into it at a reasonable price.
As you learn about the ins + outs of this little revolver you will learn the things that make one more desired than the next one. Things like low serial numbers, original stocks, box and papers. Yes, the pinned barrel models are more desireable to a collector.
