Multiple errors on type coins such as the Buffalo Nickel are unheard of. This 1920 Buffalo Nickel was struck 40% off-center on a Cent planchet.
This is one of the most spectacular and dramatic major mint errors of all time. The eye appeal, strike, positioning of the off-center design, condition of the coin and rarity all combine to make this the centerpiece of any mint error collection. This major mint error was featured in my NLG Award winning book, World's Greatest Mint Errors.
