Wow! The rare double-strike variation. That should command at least a 50% premium. I sure hope you haven't fired that gun, put it in a holster or thrown away the cardboard sleeve from around the box. That would ruin the exceptional collector value.
(Why hasn't someone developed a sarcasm font?)
Interesting, isn't it, that what a numismatist would see as valuable we consider a flaw, while what we consider sacrilege an auto enthusiast sees as value-added custom features?
I wouldn't send it back for a cosmetic issue except as a pretext if there was something else I didn't like about that specific revolver, but I spend much more time shooting my Smiths than looking at them. YMMV.
