Do we have a what’s it worth section

Buddy of mine wants to list a couple heads that haven’t be produced in years. We have zero ideas on what they would sell for.
No we don't but there are plenty of them. The bad thing is that they always end up getting taken down because they turn into a sale thread. There are always member that either want the parts or want to steal them before the seller knows what they are really worth. Not fair to the seller and damn sure isn't fair to the other sellers that play by the rules and start a sale thread. With the internet you should be able to find some sale info about them if you just do your homework.
