I assume these are representations of two of the twelve signs of the Zodiac -- Leo (the lion) and Gemini (the twins)? They could be from anywhere.
They look like little charms you attach on a inexpensive bracelet. Nothing fancy nor any reason to think they are associated with numismatics or are valuable. Is there something you left out of the thread that caused the inquiry?

Nothing wrong with your question, I think. By the way, in alchemy various elements actually have or had symbols too. Here is "gold" ... ... and this is "silver": Christian
