Hub and Die Errors
In order to produce coins, a mint needs something to strike it with. They take a steel rod and imprint the coin's design in it with a hub bearing a relief image of the design.
Hub and die errors are collectively known as varieties. If damage or some form of alteration is made to a hub or die, it is classified a variety. Modern coins are still released with hub and die errors, mainly because the defects are usually too small to be seen with the naked eye. A few exceptions exist, where the dies are used despite producing easily visible flaws. The 1955 Lincoln cent is an example.

Famous quotes containing the words hub and, hub, die and/or errors:
“We recognize caste in dogs because we rank ourselves by the familiar dog system, a ladderlike social arrangement wherein one individual outranks all others, the next outranks all but the first, and so on down the hierarchy. But the cat system is more like a wheel, with a high-ranking cat at the hub and the others arranged around the rim, all reluctantly acknowledging the superiority of the despot but not necessarily measuring themselves against one another.”
—Elizabeth Marshall Thomas. “Strong and Sensitive Cats,” Atlantic Monthly (July 1994)
“There is no object so soft but it makes a hub for the wheel’d universe.”
—Walt Whitman (1819–1892)
“Why wont they let a year die without bringing in a new one on the instant, cant they use birth control on time? I want an interregnum. The stupid years patter on with unrelenting feet, never stopping—rising to little monotonous peaks in our imaginations at festivals like New Year’s and Easter and Christmas—But, goodness, why need they do it?”
—John Dos Passos (1896–1970)
“The errors of the observer come from the qualities of the human mind.”
—Johann Wolfgang Von Goethe (1749–1832)
