Coin collecting has long been a popular hobby, but for some collectors, it can also be a lucrative one.
Let's delve into what makes this particular coin so valuable and how you can determine if you have one in your possession.
The 1970-S Washington quarter is a proof coin, meaning it was struck with specially prepared dies and planchets for collectors rather than for general circulation.
This particular quarter was produced at the San Francisco Mint, which is indicated by the "S" mintmark on the coin.
The real allure lies in a very specific and rare error associated with this coin: the overstriking of a 1941 Canadian quarter.
This error occurred when a 1970-S Washington quarter was mistakenly struck on a coin already bearing the design of a 1941 Canadian quarter.
This rare Bicentennial Quarter, discovered in an old collection, is a pristine example of an error coin.
