One reale or two?

[cti4sw]

My buddy Scotk9 found this in the same general area that my quarter Eagle and other colonial finds came from. We can't decide if it's a 1R or 2R, nor can we figure out where it was minted. The case it's in was made for a dime.

It's a 1/2 real--nice find!

Right, Erik.
1/2 R is shown as 'R', 1R would appear as 1R.
The "M" next to the R signifies Mexico City as the mint.
The 'FM' signifies the assayer(s).
The standard weight would have been 1.6917 grams of 0.9030 silver; or 0.0491 oz of silver ASW.
