My favorite bit of currency here is the 20 riyal coin. It’s worth a little less than 10 cents US these days.
The tree is called “The tree of life” and is found on Socotra island. I don’t know why it’s called that. This is a picture of the older type with what I believe is a brass center. The new ones are made from one metal, I think they are aluminum. The new ones are undoubtedly less expensive to make since they are stamped out of a single piece of metal. Abdul Summit tells me that many people cut the middle out of these older coins to make decorations for their jambiays, necklaces, etc. I like this particular coin, it has a good patina on it and makes the graphics easier to see. I’ll keep looking for a better one though.
