want to find some idea of what rod is worth

Question
QUESTION: i need to find where to sell 1968 orvis bamboo battenkill 7 1/2 ft fly rod 2 tips 3 7/8 oz line hdg6 serial number 53384 condition mint r case dirty from in closet

ANSWER: David,
Please do not quote me for prices, Please. Can I say please again ? I am getting the prices from Antique & Collectable Fishing Rods: Identification & Value Guide Homel, Dan. 1997.  You can probably find it in your local library. The 7 1/2 ft model Battenkill has an extra tip valued at  $150, 300 and $550 for poor, good, excellent condition respectively.
The battenkill was made in the 70s -80s from my memory of it. The book confirms those dates generally so apply 30% to those prices for the age of the book. Not sure what you meant by "hdg6 serial number 53384 condition mint r case dirty from in closet"
To really objectively evaluate your rods condition see
Bamboo Rod Restoration Handbook -Michael Sinclair  also available at major libraries. Most people do NOT have a mint rod who say they do.
Is there a letter with the serial number ?
see also the Orvis site has info:

QUESTION: orvis gave me date made from serial number rod was presented to my dad for large sales at his store .rod is mint only used one day in vermont .thank yuo for yuor time ps rods sold for 900 or more 1965 in dads store

Answer
David,
That is amazing 900 in 65? I have never heard that before.
Orvis does not carry the collectors value that many other makers have. I have heard "made to last not to cast" about orvis because of their heavy infused finish.
Be sure to try the resellers that Orvis recommended , the address in the previous answer,  Keane  and Codella both are well respected.
Good Luck
Mac
