If the 1804 dollar is considered to be the "King of American coins," would the 1913 Liberty nickel be called the Prince? Probably the second most famous coin rarity, the 1913 Liberty nickel has fascinated collectors for nearly 100 years. Even though it was not a circulating coin--like the 1804 dollar--it's been desirable, and attracts attention whenever it comes up for sale.
I have seen all five specimens. One was unaccounted for, for many years. A coin dealer offered a reward just if he could see it, and know it was still around. The publicity brought forth the idea that all of the known specimens be displayed at a World's Fair of Money. There was the Smithsonian coin, the Money Museum coin, one owned by a collector and another being offered for sale. Yes, the fifth coin came out of hiding. The family who owned it kept it in a closet for years, believing it was not genuine.
All five coins were displayed in a special exhibit at the convention. I went to view the coins as soon as I entered, and found a long line. I went back a second time. The long lines continued for much of the weekend.
I saw all five 1913 Liberty nickels at the same time. Now that's once in a collecting lifetime.
