Honestly, I don't know.

I've thought about getting a reference and trying to price them and if I find something I like I'll let you know but right now you probably know as much as I do. Most of the foreign coins I have mean more in a sentimental sense than anything else so I've never tried to price them. Most of what I have falls into 2 categories. 1) Coins from my grandparents' trip to South America and Europe when my mother was a little girl and 2) Coins given to me from a friend of my mother who went on trips around the world including parts of Asia.
