It's difficult to estimate the value of an error coin without an in-person examination. A dime that appears to be fully copper could have multiple causes:
The difference (and the value) is where they were made. S= San Francisco, D= Denver.
The value is just for the silver, about a dollar
The values is for the silver about $1.00
The mintmark can only be a "D" for a 1960 dime. Regardless it's so common the value is $2.00 just for the silver.
It's worth 10 cents.
the dime in 1946 was worth $1.40

If the coin is the same thickness as a normal dime, it's not copper. It's been plated or exposed to heat/chemicals that changed its color. In this case it's just a damaged dime. However, if the coin is thinner than a normal dime, it could be a lamination error. That happens when the outer cupronickel layer comes "unstuck", like taking the cookie part off an Oreo. The copper core then becomes visible. In this case it could retail for $5-6.

It may be a wrong planchet error ( 1 cent coin struck on dime planchet) but I doubt it, take it to a dealer or collector to make sure.
The value of a 1957 D dime can vary depending on its condition and rarity. Commonly circulated 1957 D dimes are generally worth their face value, which is 10 cents. However, if the dime is in uncirculated or mint condition, it may have a higher value to collectors. It is recommended to consult a coin specialist or reference a coin price guide for an accurate assessment.
A 1959 dime is 90% silver. At today's spot price of about $13.50, it is worth at least 97 cents.
