First one is famous Chinese coin called: "Why don't we cut square out of middle of coin and sell to dumb Americans".
And I think that image #8 from the first post and image #2 from the second post are upside down ... Christian
Thanks all. After your kind replies, I determined that coins 3, 4, 5 and 6 are from Japan, and the second is from Tunisia. The first is Chinese but need the denomination and year, thanks.
