The serial number would make it the 68th gun out. They didn't make that many of the pheonix guns and there was some function problems with them. By the time they switched everything over people wanted the original Combatmaster, not a knock-off. Thus the Pheonix guns are fairly rare but also not really that desireable. Did you get the gun from Gunbroker? The value of it would really depend on who wanted it. To a collector who wants it to fill a spot it might worth allot. If the recoil plug is beat up the you NEED to get a new pring in that gun before you shoot it anymore. Hope this helps!
