A lot of factors usually determine the value of factory takeoff barrels. Their doesn't seem to be any hard and fast rule.
It depends on the barrel material, contour, popularity at the moment, whether it's an individual or retailer, etc etc...
The classifieds here are about the best gauge I know of to determine what they'll bring. Those that are priced right sell. Those that may be priced a little high or the features aren't as desirable sit at asking price. You can check the retailers (site sponsors) who are usually a little higher than an individual but remember they have the associated costs of any business to cover.
Good luck.
