Error Coin Updates
New error entries are added, and auction results are updated annually. Updates in this guide are noted by the current year placed at the end of error listing.

Error Coin Collecting
Error coin collecting has been increasing in popularity, as evidenced by the growing number of error coins submitted to grading services. In 1999, PCGS was the first coin grading service to recognize error coins other than the traditional error coins like the 1955 Lincoln cent and the 3-legged Buffalo nickel. These two coins have still had spots in Whitman albums while more recent errors have not been added.
