The first is islamic coin, the second probably from China. Please, tell me something more about them if you can.
I would think the second piece is "hell money". Fake money used in different Chinese ceremonies. Paper "hell money" is burned, but I'm not sure what the coins are for.
As I know the hellmoney are prodeced to burn at the altair - to bribe evil ghosts. Very interesting tradition! Unfotunatelly, lucky tokens are very similar to coins. I hope it bring me luck
