Here are two different types. My question is about mintmarks, is it still inthe range in the 1953s? The 1954, the 5 is filled in. What is that called? Thanks for any help. Michelle
The filled 5 is known as a die chip, which is a very small die break. The S mintmark of this era was punched by hand, so there is quite a bit of variation in the placement.
Around 1990, the US Mint standardized the font and size of the Mint Mark, making the Mint Mark a part of the template or hub from which the dies are made. It is now all one process.
