I found this 1970 D penny this weekend. It appears to have an error on the S int States. It is blurry and not sharp like the rest. Is this an error and would it add to the coin value?
It's called a "Strike Through Error" "Missing Element Coins" or "Filled Dies". Another name is "Grease Coin". Grease is added to the machine allowing quicker production. Some of the grease ends up on the die resulting in lightly pressed or missing lettering. Fairly common error. It's worth about a $1.00 to the collector that wants one. The coin price would be worth more if it was an extreme type of error.

That would be a more extreme error....missing numbers on dates are a little more collectable (Hunted/Prized). Depending on the grade, that coin can be worth much more. Nice find, got a picture?
