Yes I have gone to some of the shops and didnt see any shop selling coins, but that doesnt mean, there is none there that sells them. Just means that I wasnt looking for any. And since I wasnt looking for any, means that there might be some there that sells them. Like the other person said, it's worth visiting to see if they do.
I have never seen coins there. I can't say they don't though. It's worth visiting this place at least once to get an idea of what's available.
