Hello! And Welcome!
In nickeled condition, it is not of much interest to serious collector. A good place to list it is
www.gunbroker.com , but you must transfer it between FFL holders. GB also has link to FFL network, you can find a FFL holder near you.
Gunbroker has many viewers; some are interested in nickeled "display" pistols...
Value is relative...a search of completed auctions will give you some idea...
