Colonial Mexico marks -- help please

[Rogerkent]

Hello, I think I have a couple of pieces of interest to this forum. The first is 9+ inches in diameter, has several marks, one of which is a crowned M signifying Mexico; but I wish to know more about it, who made it, and it's place in history. It has a crowned R on the top rim with the rest of the punched marks on the underside. The other is slightly smaller and is a repoussé silver dish with Spanish Heraldry with no marks whatsoever and just wanted to know more about it as well if you can help. Thank you for looking at these for me.
Regards, Roger

My apologies, I forgot to add the marks as I see them, in case a couple of the zooms are too blurry.
1- Crowned R
2- Crowned M
3- CDN
