Check these out! I bought this set of used coins on the Minsk aircraft carrier museum (see my post of Sunday July 1) for ¥120 (about US$20). The collection contains the smallest coins from some 50 countries. Notably absent, though : the venerable one penny from the United States, and the one cent from South Africa! Hmm. The set DOES contain coins from some very unusual countries : North Korea and Myanmar, for example.
