I'm am in the processing of selling off my late Father's coin collection and have come across four coins marked as "Pakistan" in the album , all dated 1964 and all have the same reverse design (crossed flags with a crescent and star symbol on both flags, with a further crescent and star symbol below the flags and, what appears to be, a hand above the flags). Despite various internet searches I have not been able to identify these coins. The coins themselves are of different sizes and different metals as can be seen from the photo's . I have tried searching under other countries that use the same crescent and star symbol but had no luck here either. Any help in identifying these coins would be much appreciated.
