Counter-clockwise, starting in the top left- hand corner, the first two coins seen to be written in Arabic. The other two coins seem to be Chinese.
the top picture (as mentioned) and the bottom picture are upside down. the bottom one is taiwan, 1 yuan, 1960 if I did my math right - year 49, started in 1911
It's a shame that you've been on CT since 2005 and nobody likes you I like your coins and am proud to have the honor of giving you your first "like" :hail: huzzah!
