Harvest Pink Floyd CDs are RoIO (Records of Illegitimate Origin, a.k.a. "b**tlegs"). They are only to be distributed free of charge. Basically Harvest is a group of floydians who spend a lot of their time and money to master Pink Floyd rare/live material for others floydians to enjoy. So, the answer to your question whether they are worth money, they are, but I'd hate to see anyone selling them. If you enjoyed them, burn a few copies for free (or for the cost of the CD-Rs) for your friends, but don't sell them.
