These are pretty much the smallest denominations in circulation of these contries at the time. Pretty common coins and some of them are in a bad shape too (like the 1 paisa or the Bahamas 1 cent). I don't think anyone bothered to make a fake version of them.
The missing 1 dirham was probably cherry-picked out, because that's the only one with at least some value: N#5590
Also the map in the middle is hilarious 🙂.
It's apparently so old that Alaska and Syberia are still connected with a landbridge. Europe is a blob. Ethiopia swallowed Kenya and parts of central Africa. Ireland still belongs to the UK.
