It looks as though the three coins in the first picture are Egyptian coins. I think the first coin in the first picture is a 1938 10 Millieme, the one on the right in the first picture looks like a 1941 5 Millieme, and the one on the bottom in the first picture looks like a 1937 2 Piastre, all three from Egypt. The coin in the last picture looks to be a 5 cent coin from Fiji, not sure of the date. Also not sure on the value any of these might have. As for the 1972 cent you talked about, I don't know about that one. Hope this helps!
