The $35,000 Error: 1970-S Quarter Struck on a 1941 Canadian Quarter
The most remarkable 1970 quarter is a proof coin from the San Francisco Mint, erroneously struck on a 1941 Canadian quarter. This minting error resulted in subtle remnants of the original Canadian design visible beneath the U.S. features. Such overstruck errors are exceedingly rare, making this coin highly sought after by collectors. In 2016, this unique coin was listed on eBay for $35,000, attracting significant attention from numismatists.
Identifying Valuable 1970 Quarters
While the $35,000 quarter is unique, other 1970 quarters can also be valuable, especially those with mint errors or in exceptional condition. Here’s what to look for:
- Mint Marks: Check for the mint mark on the obverse side, to the right of Washington’s ponytail. Absence of a mint mark indicates Philadelphia; a “D” signifies Denver; and an “S” denotes San Francisco (proof coin).
- Proof Coins: San Francisco proof coins, especially those with deep cameo contrasts, are more valuable.
- Mint Errors: Look for anomalies such as double strikes, off-center strikes, or coins struck on incorrect planchets.
- Condition: Coins in mint state (MS) grades, particularly MS67 or higher, command higher prices.
