This continues around most of the coin  and is only visible under a microscope

That is a die crack, dies fail at some time due to the immense pressure that goes into striking coins.   There are some coins that have multiple die cracks and those coins were struck just prior to the die falling apart.   This is very common on some series of coins and more unusual on others, while interesting it is not considered an error.   Die cracks are used by some to help identify die states and can help in verifying counterfeits.

CB's right. To amplify, a die state is the phase of its working life that we can see in the coin's details. For example, I have a 1794 cent that has a crack through the 4. It is middle die state; early die state would be when the die was new, and late die state was probably near its point of failure. Concentric cracking around the lettering on 1800s dies is by no means uncommon. I'm not sure whether there is a book on all the die states of all the cracks, or if anyone would bother since most of them don't add much of a premium.

Thank you for the information
