That is a fine looking 3" model 10!
i have a modest 3” K frame collection. Attached picture is missing 4-5 that I picked up in the last few months. With that being said, the 3” 38’s (mod 10 & 64) bring less than the comparable .357 magnums (model 13 & 65. Model 66 is in a different zone itself). Watching auctions, forums and classified ads I would say your gun would sell for $650-700 from person to person. In a gun shop probably $50 more depending on location. On GB Auction all bets are off. Ii just depends on who sees it and if you get a couple of motivated bidders, it could go for more. If it were passed down to me it would be priceless. I’d shoot the snot out of it and get mote enjoyment than any amount of money I could getHi guys & gals. As hard as I've tried, I just cannot get anyone to commit to even a round-about ballpark figure on the approx. value of this beauty. Most people I've spoken to, or chatted with, agree that's it's valuable, but no one will commit to a figure. Is it really that hard to value, or is it like one gentleman told me; That I have to have it appraised by pros. If anyone can help. please.....DO! Thanks for all the help you've all been to me! 😎 p.s. I remembered today that a letter of authenticity already exists on this piece from Smith & Wesson, written by the late, great, Roy Jinks! I'm going to my storage this week where I keep my dad's things. I will find it. Dad was pretty meticulous. 😎😎.
