1804 Peru 8 Reales -- Real? Silver Counterfeit? Fake? Old? New?

I would appreciate comments about this coin that was my deceased uncle's. I know these are commonly counterfeit or fake, but I do think this one is silver. Here's what I've measured:
Diameter -- 39.3 mm
Thickness -- 2.5mm
Weight -- 26.38g
Specific Gravity --10.185
Interaction with a moving rare earth magnet -- it reacts like my other higher silver content coins, moving as the magnet moves along near it.

I've included observe, reverse, and two edge pictures. Thanks for any input.

Looks funny, but it has had the crap polished out of it and its too bad, I can't blow your photo up to get a good look. Try the ice test


I would be interested in this, real or fake, but I dont think much of value because of how polished it is, and holed.

Here are some larger images I was able to make with my scanner. Thanks for the input. Since the coin was my uncle's I plan to hang on to it.

It looks real, just been polished to oblivion, the hole is also very old, it wasn't made with a drill bit. Still an interesting coin, enjoy.
