Is this 1971 Half Dollar error a lamination error?

I got a few half dollars rolls to go through and came across this one. At first I thought it was PMD, but after taking a second look I realized it was an error of some sort. I am guessing @paddyman98 among others can identify this in a blink of an eye. Thanks!

Hi. Yes.
It's called a Rim Burr. Not a Lamination.
Mint Error.

1971, my birth year

 

Here's one from my collection..

 

Just out of curiosity, did you have that slabbed or buy it slabbed. What would be the value on something like that?

 

Hey I’ve got a question? What causes a rim burr?
