Hors devours Spoon & Pick Set - High Purity Mexican Silver

Hi Everyone! Took me most of the week to get this set polished and ready to show. I bought these the woman said they were not silver, and boy were they dirty! I figured I would give it a shot for a few bucks. Turns out they are silver, my test showed higher than 92.5 or Sterling.

I am not sure about this, but I theorize that these are several sets put together. All have really nice detail with different Mexican/Mayan finials. The picks have tiny hooks on the back, I am guessing to either help with grip or to hang off an appetizer plate. If anyone thinks they are something different please let me know. I am not sure if they are old or valuable, but at the very least it is 2.5 ounces of silver. Thanks!!!
