1979 Washington Quarter Error

In a recent auction, a coin with a ’79 Washington quarter error sold for $13,200! The coin is actually struck in Philadelphia and was probably struck at the same time as the quarter. An amusement-token feeding mischievous mint worker may have caused this quarter error. However, it’s likely that the coin’s maker was simply mistaken. This error is one of many that affect coins. Listed below are a few examples of the problems this coin could have suffered from.

A two-headed quarter is also referred to as a mule. It was struck on a different planchet and rims than a normal quarter. Because it’s different in size, it’s impossible to determine which one is which. A double-headed coin has a different ring than a normal coin. Oftentimes, a two-headed coin was struck by mistake. The mule was struck on a softer silver planchet, but the coins’ design is identical.

The extra-leaf low coin was minted in Denver in 2004. It is rare to find a coin in this grade and is a relatively low-grade error. A high-grade specimen can achieve a price of over $275. A rare coin in this grade will be graded by PCGS, which stands for Professional Coin Grading Service. The rounded tool was positioned in a different position on the coin, making the additional leaf appear low on the husk of corn.

The Minnesota quarter, minted in Philadelphia, had a lot of error coins. There were more than 50 varieties of these coins, most of which featured a double-die on the reverse side. PCGS graded a number of different types, which included some that had an extra treetop. The most famous of these varieties, FS-801, was a ghostly spruce that was located just to the right of the fourth tree on the map.

The original obverse portrait of George Washington was not used for the 1979 Washington quarter. The San Francisco Mint added the P mint mark in 1980. In the 1960s, the Philadelphia Mint stopped striking clad Washington quarters. Afterwards, the coins were changed to a new design with the American eagle clutching arrows. Those coins were the first to feature the P mint mark, which had previously been not present. Previously, the obverse had the United States of America on it, and the Quarter Dollar was shifted to the right.

This error can be caused by many reasons. A die that has become stuck to the planchet, which caused it to be off-center, caused the coin to be struck again with the wrong image. In some cases, metal shavings from the coin struck into the obverse has popped out. This condition is called ‘brockage’, and is not unusual in the coin market. The odds of two identical events occur are too great.
