Confused_Seeking help

Here's a picture of the reverse side of the coin.

Hi everyone, Thanks for taking the time to look through my message. I have recently found an 'Anna Dei Gratia 1710 coin' well at least that is what I believe it to be. I have looked at so many sites online & read so much information, that now my brain is in overload mode & I'm really not sure what I'm looking at anymore. So I would really appreciate it if someone could please help me out & tell what it is I've actually found.
