Best time to sell "collectors" calls

[wkyhunter]

Hi all!
I have some questions for the experts before the boards get quiet.
When is the best time to sell a couple of production calls that some may consider collectible?
I have a couple of Quaker Boy Grave Digger paddle box calls that I'd let go of if there is interest.
One is in original package, two are without package. What is a fair price range for them?
Also, where is the best place to sell?
Thanks in advance.
