Spent some time looking at the book and decided the best thing is to give you what the first page introduces: It states that the book is a fully illustrated catalog & price list - 1616 to date (*1966) and includes a brief history of American coinage, Early American coins & tokens, Early mint issues, regular mint issues, private state and territorial gold, silver and gold commemorative issues, proofs... and looking briefly at the pages i didn't find any headings concentrating on error coins. Hope my long winded answer helps. Enjoy the weekend.
