<<Here is a copy of The Official Price Guide To Mint Errors 7th edition of which I was the editor. Interestingly, the author wanted me listed on the cover as coauthor as he was getting older and just wanted to pass it on but I didn't feel right about being called an author for something that was 90% his work -- though I did make a lot of photographic changes for this and the 6th editions and did write a few new chapters in addition to my editorial work. So the publisher did take my name off the front cover as a coauthor but left my author's bio on the very last page of the book. So in the end I'm still a coauthor like it or not. Ha!
This book is now hard to find and the last time I looked used copies were selling for about $60 to $80 on eBay and Amazon. Maybe they've come down - don't know. If you want one settle for the 6th edition at a much lower price. Very little difference in them. Many more were printed and thus the lower price.>>
