The 1962 Jefferson nickel had indentation on the forehead and it appears outwardly on the reverse under the Monticello. After looking and re-looking at it, I'm of the opinion that this is a mint error. Tell me I'm wrong! Or tell me I'm right! The 1964 D with the 'gouge' going across the forehead, I feel pretty comfortable in saying that his is also a mint error. The 1964 D that had the die marks or cracks run up Jefferson's nose. Please take a look and let me know what you think. I go through thousands of nickels and came up with these 'interesting pieces. Thank you all.
