The 1763 coin is a Spanish Reale. It's called a "Milled Pillar" type coin, from the Mexico City mint. Like the one in my avatar. The "M" with the little "O" above it means it's from the Mexico city mint.
I'm not sure of the denomination though. The coin in my avatar is a 1 Reale, and it's the size of a Nickle.
So if your coin is smaller than a Nickle I'd say it's a Half Reale. Cause I think the 1, 2, 4, and 8 Reales, all show the number on the back. For example R-1, R-2, etc.
Wow, see the stuff you learn when you dig up a coin! lol.
One year ago I didn't know any of this.
The last coin is another Spanish Reale coin. A "Carolus", or something like that.
And If I'm correct, I believe they came out AFTER the "Milled Pillar" type coins.
Someone else could probably help you out alot more than me about this one.
And I have no idea what the first coin is. Sorry.
Did you find these coins detecting
I believe the 1763 coin is a 1/2 real because to either side of the shield is a rosette; not seen on the 1R coin. If a 1/2 real, the diameter is 16MM. The Carlos III 1/2 real was minted between 1760 and 1771. The crown on the reverse left column is 'imperial' while the one on the right is 'royal'.
The coin below the 1/2 real is from the reign of Carlos IIII (or IV): 1788-1808. Since there is shown no reference to size (like a US penny), I can offer up that the coin is a 1/2 real if 18mm, a 1R if 20mm and a 2R if 28 mm in diameter. The (unreadable to my eyes) date of the coin is under the bust of Carlos.

Digger:
What appears, if anything, on the reverse side of that 'coin' #1?
What is it's diameter? It looks like an obliterated cob coin with a large incursed overstamp, reading M-ZENxx
Thanks,
