Query: Goldmine Record Album Price Guide

This book was a big help in determining price for each record. However, when I took the records to a record store to sell them they were not worth as much as the book claimed. It is probably because the book is based on collector prices and I have not looked into selling to a collector. Overall it's a great book especially if you don't know anything about records.
