Questions about Dimes, trying to learn!

I have three dimes that I am curious about.
Can you tell me if there are common terms describing their abnormalities, or if this is damage done from an outside source? Also can anyone help me identify the dime whose date is cut off?
Thank you!

The dime is dated between 2010-2018. In order to help you with these coins we would need pictures of both sides of ea h coin.

 

Here are the backs. Sorry I know its confusing.

 

post mint damage.

 

1992P = PMD (post mint damage)
1985D = worn died. Common on many dimes in the 80s. No additional value
20??D = PMD. Looks like it was pressed. Notice how the rims are flat and wide andthere is no detail on the high points. It probably has a slightly larger diameter than a normal dime.

Hope that helps
