gunbroker has a reserve auction feature, whereby you can list an item with a low opening bid and a high hidden reserve. say $500 and $2500. let it run for a few weeks and see what bids and questions you get. then relist it in as many venues as you can find, with a fair market retail price and see if it sells. if it does not sell, get back to us.

You could just join the PGCA get a reduced cost on a letter and list it here in the Members Only for sale section of this forum. What better place to sell a Parker than here?

Why not put on Gunbroker and let the market determine
The value, put a $ 500 minimum on it and let the bidding begin
As you said nobody in you family wants it

Damn shame nobody in the family wants it, The old gun is sort of like a red headed stepchild that no one wants, Hope someone will by it and take it to field, come to think about it this would make a good story about the gun nobody wanted, Gary
