I believe what I have here is a contemporary 8 reales counterfeit dated 1814. Would my assumptions be correct? I believe the assayers initials on this piece are engraved as RG, which is an initial set that doesn't exist. After weighing on a balance, the mass came out to be 24.40 grams. The sound this coin makes when doing a ping test sounds similar to this piece: https://en.numista.com/catalogue/pieces30223.html I'd say this piece has some silver in it, but it's very debased.
