Hello All,
I am new to coin collecting and came across this 2008 quater while CRH. I don't know if the damage is manmade or by the mint. The weight is the proper weight and the rim is not damaged where the coin is? Is this a error and if so what kind? 
Thank you for any help.

Interesting, looks like post production damage but the pictures, although not bad, just don't convince me completely.

Looks to be post mint damage. OR maybe some planchet deal??? Nasty coin. But cool as well.

Looks like damage after the mint the edge tells me its clad

It’s post mint damage for sure, I don’t know how that happened, but it’s been through the ringers for sure!

Very nice pictures by the way.  However, I strongly agree with the majority consensus here, and that the damages you see occurred post-minting.  Have you searched online for other examples, or did the mint publish anything about error coins with those type of markings?

I belive its an error from the mint, possibly a scratched die or something that was caught on the machine and was stuck, scratching the coin to bloody hell. Of course that's just a theory. 

Definitely PMD. There's no point, start to finish in the minting process where something like that could've occurred with any likelihood. It looks like the victim of someone who has been cooped up at home for too long with a garage full of tools just itching to be used - some people out there have way too much time on their hands, and it seems someone out there decided to offer up numismatic sacrifices to their bench grinder. (At least they could have done something cool like make a Hobo quarter or something else - Maybe they could've made the bear into a fisherman? Or change the fish into a shark attacking the bear? That'd be cool!) -Sam Gelberd, ANA Numismatic Educator.

You could.say. Of with there head!

Definitely looks like post mint damage to me.
