Help Me Obi Wan... | Spain 1/2 Real 1812

I'll try my best, but...


It's a Spanish (or Spanish Colonial) silver coin. Rotate the bottom pic about 120 degrees clockwise, and you'll see the Spanish coat of arms, with the words "HISPAN ET IND R" around it; given the "R" is abbreviated rather than the full word "REX", this must be the small 1/2 real coin. The mintmark is Mexico City.

The obverse should show the Spanish king, but it's pretty mangled. The first letter of his name is clearly "F", so it must be from the reign of Ferdinand VII. Click on this Wikipedia page and scroll down to the Ferdinand VII coin on the right hand side; your coin should look something like that.

The date below the portrait is 181?; I can't read the last number but I think it's either a "2" or a "9". Those two years have different shaped busts of the king, but the portrait on yours is too mangled to tell for sure; I think it's an "armoured" bust, making 1812 more likely.
