I think for a really nice one that is correct to include a real deal headlight about $2k would be the upper limit. Although always a popular bike it seems to me the market for these has cooled in the past few years. I know some will point to the poor specimen that sold at Copake a few years ago for $5k but I consider that an anomaly. That bike was bought by the BMA who overpaid for a lot of stuff. I don't believe you can apply a linear inflation model to collectibles because of a lot of variables. The Bluebird is a good case in point. 20 years ago these brought around $12k which is just about what they bring now. Some of the more obscure stuff has found greater appreciation in recent years e.g. Huffman Safetys and Super Streamlines. Personally I don't look at bikes, or any of my collectibles, as investments. Thats why I have a 401k, IRAs, and stocks. Sure, at the end of the day I would like to see something back to leave to my heirs but this is a hobby meant for enjoyment. Worrying about whether I'm going to get my money back saps the fun out of it! V/r Shawn
