Doubled die shows strong increase

Has the 1955 doubled-die cent risen constantly in value since its discovery?

Has the 1955 doubled-die cent risen constantly in value since its discovery?


A little study of this and other significant minting varieties shows that there is usually a trough after the initial discovery and rapid rise in price, followed by a more or less steady increase in value. The 1955 cent for example in 1975 was at $425 in BU, dropped in the interval to around $350, and in the 1980s had climbed to $650 in MS-60. The most recent quote (2010) is $43,500 in MS-65 grade.

Some newspaper listings for gold (and silver) list the weight in kilograms. Please convert this to understandable terms.

There are 2.68 troy pounds in a kilogram, or 32.16 troy ounces, so to find the value of an ounce of gold or silver in a kilogram bar, divide the bar price by 32.16. Don’t forget, the U.S. officially is on the metric standard.

At least one source claims that the Mint coining department was still making coin dies until the 1880s. Is this correct?

Renowned researcher Robert Julian refutes this claim, pointing out that in 1853 Mint Director Snowden ordered the coining department to return control of the die making to the engraving department, where it belonged.

What’s the difference between a vertical elongated coin and a horizontal piece?

The terms refer to the relationship between the axis of the design and the elongation of the coin. A vertical design is upright when the elongated piece is standing on end, and a horizontal design is upright when it is on its side.

Please send me a list of banks in my area that participate in coin programs.

Compiling such a list would take a considerable amount of time, and you would get more up-to-date information by simply Googling online or picking up your phone and calling your local banks.
