What makes you think it's misprinted? There are no mind readers here, we actually need a hint. BTW, coins are struck not printed.
It's a friends coin and she said the coin is new and the "United States" on the back side is the misprint. I don't really care too much about the terminology to be honest. I'm just a random dude with a coin not a enthusiast...
The silver content is worth .18084 times the melt value. This is probably more than she would probably get for the anomaly which I can hardly see in these photos. Chris
An obviously circulated coin minted in 1964 is not new. I see what you are talking about. It's probably some damage inflicted after it was minted.
After enlarging your photos, I can see that it was struck with a grease filled die. It's very common and adds no value to the coin. It's worth melt, which at the moment is $3.1557 (rounded, it's $3.16).
I don't think so. Look at the first picture and the third picture. Notice in the first picture the quarter is closest to the word misprint. Now look at the third picture. Notice how the quarter is closest to 1964d. The coin is sliding in the holder giving it an appearance of a rotated die. It's just a normal 1964d quarter with nothing special.
First, the now year-old question seemingly had nothing to do with a variety, so it's unfair to state that anyone was "wrong". That said, you must have incredible eyesight...
