It's unlikely that a damaged barrel that old has any real value other than as scrap metal, but to find out for sure you'll have to talk to Eric directly. If you call early in the day you should have no trouble reaching him.
Depending on the year make and model, the prices range from $25 to $75. That is assuming that the bore needs repair. If the bore is good I'd suggest trying to sell it on Ebay, you'll get top buck out there.
