Your resale value will hold up as long as the gun is cared for.The 2 I have are a set,they came in a case with scrolled cylenders and frames and are matching with 7 1/2 in barrles I bought them used.I use them all the time,it don' t matter if they have 1 shot or a 1000 shots through them they are still used and hold the resale as long as they are still in excellent condition.
