The issue is that the post that would form the center of the mintmark, has broken off that die. This is a common find and will continue to retirement.

If the post broke off of the die, then it could rise above the top of the mintmark:

These are just die events. They add no premium to the coin. Just something the eye will notice, but now we know what it is and can move on to the next coin.

Broken post? What is that? on closed devices, if the post break off of the die, it can appear that there is no center of the design. with the post broken on a closed device, that area will be shallow/filed/rise above the device. different from a die chip. no premium for these though.
