Pattern coin

Regular coin (left), pattern coin (center) and piedfort (right)

A pattern coin is a coin which has not been approved for release, but produced to evaluate a proposed coin design.[1] They are often off-metal strike, to proof standard or piedforts. Many coin collectors collect and study pattern coins because of their historical importance. Many of the world's most valuable coins are pattern coins; nearly one quarter of the pieces listed in 100 Greatest US Coins are pattern coins.[2]

English patterns

The first English coin that can be identified with certainty is a groat, originally worth fourpence. This piece, an example of which was illustrated and sold in the Dodsley Cuff sale of the mid-19th century, had crowns in place of the usual three pellets in each quarter of the reverse.[citation needed]

Patterns are particularly identifiable and exist in larger numbers from the reign of Elizabeth I onwards. The experimental base metal issues of all coinage prior to the mid-18th century have been well preserved.[citation needed]

Boulton's mint in Soho produced large quantities of patterns, which were supplemented by Taylor some fifty or so years later from the same dies.[citation needed]
