It sounds like you've found some old pesos. The emblem with the animal is probably a bird of some sort (they made them look really rough and tough back in the day). Unless they were taken out of circulation entirely, you probably won't get much (if anything) for them. Since you don't have an image of them I can't say I'm entirely sure but from the description I'd be willing to bet that's what they are. To be sure, take them to a local coin shop and have someone check them out.

ill try to upload a few immages in a bit I asked some people and they said they wer pure silver and gold and anything I've found for prices said the gold one was worth 867.12american$ and the silverone any were from 224.15-438.47american$

I think the animals are sumsort of lion and an eagle the coins look like they are early 1700's it will take me a bit to get images because my mom has the camera and shes not here ill try and find sum on google
