If these kind of data are of any interest to you, you will definitely want to bookmark this site. To the best of my knowledge, it's the only one of its kind on the net and the owner, Alec Nevalainen, updates it on a regular basis. I've been checking it about once a month for the past couple years. The "about" page is an interesting read and the "countries" page shows which countries' coinage, besides the US, he keeps track of. All in all, an excellent site.
