What Is the 1970-S Proof Washington Quarter Struck on a 1941 Canadian Quarter?
The Error Coin
The 1970-S Proof Washington Quarter struck on a 1941 Canadian quarter is a rare numismatic mistake that occurred during the minting process at the U.S. Mint. Normally, proof coins are struck using specially prepared dies and planchets (metal discs). However, in this case, the U.S. Mint accidentally used a 1941 Canadian quarter planchet (a blank metal disc meant for Canadian coins) to strike a 1970-S Proof Washington Quarter.
Why Was This Mistake Made?
The reason this error occurred is not entirely clear, but it likely happened due to a mix-up or error in the Mint’s inventory. A Canadian quarter, which is similar in size and composition to the U.S. quarter, may have been mistakenly included with the other planchets meant for the U.S. Mint. As a result, when the proof quarter was struck, it ended up on a Canadian quarter planchet, creating a unique and highly collectible error coin.
The Impact of the Error
The striking of a U.S. quarter on a Canadian planchet made this coin stand out from other regular issue 1970-S Proof Washington Quarters. The 1941 Canadian quarter planchet has a slightly different composition and weight compared to the typical U.S. quarter planchet, and the difference is noticeable to collectors. The coin has a unique look, with a blend of U.S. and Canadian features, making it a true oddity in the world of coin collecting.
Features of the 1970-S Proof Washington Quarter
Size and Composition
The 1970-S Proof Washington Quarter, when struck correctly, follows the standard specifications for U.S. quarters. It has a diameter of 24.3 mm and weighs 5.67 grams. However, because the 1941 Canadian quarter used as the planchet has a slightly different composition, the final coin struck from this error can be distinguished from others by its subtle differences in weight and feel.
Canadian quarters from 1941 were typically made of 80% silver and 20% copper, which gives them a distinct metallic quality. U.S. quarters from the same period, however, were composed of 90% silver and 10% copper. As a result, the mixture of metals used in the struck error coin gives it a unique texture that sets it apart from a regular 1970-S Proof Washington Quarter.
Design Features
Like any 1970-S Proof Washington Quarter, the coin features a portrait of George Washington on the obverse (front) side. The reverse side shows an eagle holding an olive branch and arrows. These features are typical of the Washington Quarter series, which has been in circulation since 1932. However, the main difference in this error coin is the slight variation in the thickness and color of the coin due to the different planchet.
