How or where can I find pipe values?

[Commander Quan]

There is nothing out there on the web or in print that is a "Blue Book" type price guide. With Thousands of carvers and tens if not hundreds of thousands of lines it would be imposable to do.

For good condition estate pipes a decent guideline is they can be bought for half of what they cost new. If your selling or trading one to a B&M expect to get 1/4 to 1/3 of what it cost new.
