These aren't errors, since they're intentionally there on the die (it's part of the minting process cleaning up damage on the die). These are called Die Scratches. These happen, when they have to polish down the dies with abrasives, do to a Die Clash event that happened. Die Clash events leave permanent damage on the coin die, so they polish it down, to get rid of the Die Clash marks. This will also extend the life of the die a bit longer as well.
