1778 Spanish coin

[Valor1939]

Hello, I have a coin that I've been wondering the value of, or atleast an estimate. It's a Spanish 1778 coin that has King Carolus III on it, then I believe "DEI GRATIA". It's a little hard to read. Thank you for the assistance!

I forget to mention it is silver.

Upon further research it is a Mexico City mint, & 8 Reales. I'm not syre of the value though.

Those don't pop up very often but lately they have been posted a lot on here. I even found one about a month ago.

As is a pic of both sides is always welcomed.
What are the assayer's initials? (just past the Mexico City mint mark.)
