This unique collection was featured on the first page of the International Section of the Jan. 13, 2003 Issue of Coin World.
There are approximately thirty known genuine two-headed or two-tailed coins that have been authenticated and certified by ANACS, PCGS and NGC. There are only four known "Two Tailed" U.S. coins: three Quarters and one Dime. One of the Quarters recently sold for $80,000.
Most of these world coins that were struck with either two obverse or two reverse dies have been handled by Mike Byers of Byers Numismatic Corp. Two of these are Canadian Copper Cents that were struck with two reverse dies and authenticated by PCGS. A few others from this collection of two headed and two tailed coins are featured below.
