Hey man, Welcome to CoinTalk! Looks like a hit to the cheek(damage) and a hit/or small die chip to the lip.
More PMD or Post Mint Damage. Try to keep yourself busy by taking the time and reading about the many errors that occur before and after the mint. www.error-ref.com
Welcome! I think these aren't errors, just the coins' battle marks. Keep looking though, because these two quarters have many errors reported. Do you coin roll hunt?
Before posting be sure to research your coin at error ref.com. You should be able to find the classification or category of the error. In your post include what you see that makes you think it is an error and what you found out in your research. The way you are posting "what error is this" or "is this an error" gives the impression that you are not making an effort to do your homework first. This may dissuade people from helping you.
