Very nice find, and a great caliber. I assume that this will be a safe queen since it's in NIB condition. Unfortunately, I'm not sure if it will appreciate much over time as is the case with most commemorative firearms. I'm not a collector and only have one commemorative...a 1973 Texas Ranger set (Model 19-3 and matching bowie knife). It's been shot but that's OK with me. It is probably one of the nicest Model 19s that S&W ever produced and it has some great features. Your Model 25-3 would probably be an excellent and fun shooter, but I can understand wanting to keep it pristine. Enjoy!
