If you do a web search for fly rod brokers, or look in the back pages of either a Fly Fisherman or Fly Rod and Reel magazine, you can find addresses of brokers or resellers of used bamboo rods. They can tell you what it's worth. Some of them have web sites that may have similar rods on them, so you can see prices.

Values will run from nothing to several thousand dollars for old bamboo fly rods. The high dollar ones have to be in great condition, from certain well known manufacturers like Leonard or Payne. I wouldn't go shopping for new cars just yet.
