@nr, first welcome to CCF. Second, I've taken the liberty of cropping, enlarging, and enhancing your pics. The second image may show Kufic script, but I'm not seeing much remaining detail on the first. As an aside, you should absolutely flatten the staples on all of your 2x2s so that they don't inadvertently damage adjacent coins.
