Two Classic Phoons just sold on ebay. Both for between $457 - 482 (I rounded up to the nearest dollar).
I wonder if the smaller paint is hurting the value of the phoons.

The 2nd one was in very close to mint condition w/ a nickle reg and matching highlights.
My guess on value would be between $300 - $400. Good Luck with the sale. You may do better in the Spring.
