Howdy and welcome.
Your coin appears to have been damaged after it left the US Mint. This would be known as post-mint damage, or PMD, and does not add any value.
Good luck in your collecting!

This one is worth ten cents.
Don't bother.
The coins that you've shown are worth face value. That means they are only worth the value shown on the coin. You should be spending them, not trying to sell them.
