Charles I Scottish Shilling - Real?

Thank you @Princetane for your thoughts! Not sure what mint it could be, I've only just gotten into Caroline-era coins. I thought it might be from Falconer's anonymous issue in Scotland around 1641-1642.

Also, what exactly would cause damage like this? I'm assuming the crack is most likely from the striking, though there are several slight dents around the portrait that makes a rectangle. Also looks like some slight bends at some point. It might have been part of jewelry at one point?

. Just a FYI: always best to remove coins from holders, especially 2x2 holders before taking photos.

Thank you all for the welcomes and thoughts! It's super neat that it's the last issue for Charles, minted just before the start of the Civil War. I managed to get some pretty nice photos using a macro lens for my phone. Not sure why it looks so brown, the colors on my phone must be off.
