The value of a 1970 quarter can vary depending on several factors, including its condition, mint mark, and whether it has any errors.
- Circulated vs. Uncirculated: Most 1970 quarters found in circulation are worth their face value of 25 cents. However, uncirculated coins can be worth significantly more, ranging from a few dollars to several hundred, depending on their grade and scarcity. For example, a 1970 D Quarter in circulated condition might be worth between $0.30 and $0.85, but in pristine, uncirculated condition, it could sell for as much as $110.
- Mint Marks:
– No Mint Mark (Philadelphia): These coins typically hold face value in circulated condition. Uncirculated examples are more valuable, [according to BOLD Precious Metals] . A 1970 Philadelphia Mint quarter graded MS60 might be worth $5.
– “D” Mint Mark (Denver): Circulated quarters with a “D” mint mark are also generally worth their face value, but uncirculated versions can fetch higher prices. A 1970-D Washington Quarter graded MS60 can be purchased for $4.
– “S” Mint Mark (San Francisco): Proof coins from the San Francisco mint were specially made for collectors and often command a higher value than regular strike coins due to their higher quality. For example, a 1970 S Proof (Standard) graded PR69 is valued at $14. A 1970-S Proof Deep Cameo graded PR69 DCAM is valued at $455.
- Errors: Mint errors can significantly increase a coin’s value. Examples include:
– “Thin Quarters”: These 1970-D quarters were mistakenly struck on dime-thickness planchets (metal blanks). They are valued from $30 for moderately worn pieces to $350 for uncirculated examples.
– Doubled Die Obverse (DDO): These quarters show doubling on the obverse (front) of the coin, most noticeable on the date. They can be worth hundreds or even thousands of dollars depending on the grade and severity of the doubling.
– Doubled Die Reverse (DDR): These coins feature doubling on the reverse (back) side of the coin. A 1970-D Washington Quarter with this error can be worth between $1,000 and $3,000.
– Overstruck Coins: The rarest and most expensive 1970 quarter is a 1970-S quarter struck on an 80% silver 1941 Canadian quarter, valued at $35,000. Another rare overstrike is the 1970-S quarter on a Philippine 25 centavos coin, which sold for $4,600 in 2010.
In summary, while most 1970 quarters are worth their face value, uncirculated specimens, especially those from the San Francisco mint, and particularly those with errors like doubled dies or overstrikes, can be quite valuable to collectors. If you believe you have a rare or error 1970 quarter, it is recommended to have it professionally appraised and graded to determine its true value.
