Your Heddon bamboo rods are in some demand. Generally, rods 8 feet and less command higher prices than those 9 feet and over. Heddon's top grades in decreasing order are: President, 1000, Expert 125, Premier 115, Deluxe 60. Some of these in shorter lengths may go for over a thousand dollars. The next (mid quality) models include the Bill Stanley Model 20 and Black Beauty Model 17. Cleck auctions on ebay under bamboo fly rod.
