I would say the value depends on the collector and the condition of the saws, but generally speaking - yes there is some value to them. Most Buck Collectors specialize in the knives, but I know some, myself included, that like to acquire anything BUCK - knives, clothing, the old darts, saws, multi-tools, old ads, etc.
If you are curious as to what they might sell for, run a search on eBay...
