What Is a Quarter Planchet?

A quarter planchet is a tool used in coinmaking. Its name comes from its shape and the fact that it has two flat surfaces. The smallest side is smaller than the other. A quarter is struck on a solid disc, while the largest features a ribbed edge. A quarter planchet is usually heavier, but some coins can be made with smaller ones. A quarter can also be a bit wider than it is tall.

Modern coin presses use hundreds of pounds of force to strike the metal into the final image of the coin. The rounded shape of the planchet is created by raising the rim of the metal disc. The metal is then struck, or pressed, at the US Mint in order to form the final image of the coin. The Philadelphia Mint can produce around 47,250 coins per minute using sixty-three coin presses, while the Denver Mint can create forty-five thousand a day with 54 coin presses.

A quarter planchet may also be an error coin. Its shape is distorted, which is called a Nevada quarter. The missing design elements may be caused by improper settings on equipment, or by a metal strip that was intended for another denomination. A quarter planchet can also contain a lamination flaw due to metal impurities or internal stresses. These errors may cause the coin to appear uneven, peeling, or split.

Another error coin is the 1963-D Lincoln Cent. This coin was struck after a split planchet. This mistake was made during the minting process and was later sold for $216. Today’s coins are made of multiple layers of metals. These cladding layers may peel or fold, and in some cases they completely separate from the hubs on which the coin is struck. A planchet will contain a die that has multiple layers, and can be fed into the press wrongly.

An error may also result in a nearly blank planchet. If it has reeded edges, it may be a die adjustment strike. These strikes can be worth anywhere from $20 to $40, depending on the type of coin and depth of the strike. The value of a die adjustment strike is dependent on how deep it is and how deep the coin is struck. However, a coin die mistake may leave a faint impression on the blank.

The Wheeler Family discovered this coin decades ago in their collection. It is extremely rare for a 19th-century coin to be struck on the wrong planchet. The wheeler family was able to date it between 1871 and 1875 with NGC’s die diagnostics. This coin was struck on the incorrect planchet for the first time in its life, and as such, is an incredible discovery. It has a luster and rarity not seen in many collections.

In 1971, the Denver Mint made two puzzling wrong planchet and off-metal errors. A Jefferson 5-cent coin struck on a blank punched from copper-nickel clad dime stock and a half dollar that was punched from a contemporary Panama half-balboa stock. These errors are rare but still a cause for concern for coin collectors. In the meantime, the mint will continue to strive to eliminate this type of error.

Coins struck on the wrong planchet are sometimes quite valuable. While not all wrong-metal errors are valuable, many are common and are worth more than the coin itself. The most common examples are the Eisenhower dollar, the Roosevelt dollar, and the Lincoln quarter. Some of these errors can be rare and expensive, so if you are interested in collecting them, you should invest in a planchet inspection service. It’s best to buy a quarter-sized planchet and make sure it fits the exact date of the coin you’re wanting to make.

Silver quarters were struck using a 90% silver planchet for 1964 and 1965. Afterward, the production switched to a clad composition planchet, and these coins have become collector’s items, fetching over $7,000 each. These coins are heavier than regular clad 1965 quarters and have no visible copper around the edge. In addition, they’re more valuable than silver quarters struck on 90% silver planchet.
