No one in this hobby spends more time and thought than you on chips and their collector value. Not to put down other books, but accuracy is key for me. I just don't get the information that I need about rare chips from other books like I do from yours. I hope that you don't get discouraged from your work by others. I bought my book from your and would not consider another source. Getting only $.30 a book is a pittance compared to the work that you put into it so the love for the hobby is very apparent to me.
