Do not shoot them!!!! Shooting them will definitely lower their value! I would wipe them down very well to prevent any damage, take great pis of them and put them on GunBroker. The original 39s are turning into real collector items. If you look on there right now, there is a serial number 63xxx that is in the same condition and is already up over $900.
I would put them on GB as a set and put the starting bid at $2000. I would be surprised if the bidding frenzy did not push it close to the $2250. You can buy a lot of shooters for the price you'll get out of these. Or, you could offer the set first for sale or trade to the awesome people here on the forum.
Or, do not shoot them and tuck them away for a future sale. Only problem is, the 39 seems to have really surged in collector value as of late and you never know when a collector "bubble" will pop.
That would be my opinion. Good luck.
Also, I do not shoot my 39 because I am afraid I will break the extractor (nearly impossible to find) and I shoot my 39-2 all the time and LOVE it. Buy a 39-2 shooter and shoot the heck out of it.
