Coin and Insignia?

[Argee]

Can you help me identify these new finds. One item looks like a coin while the other item is really giving me trouble to identify it. They were excavated underwater in a late 17th century shipwreck, (Please see pictures). Thank you!

The coin is a Chinese cash. Can't see the details clearly enough to identify the type, but you can probably match it up with one of the Ch'ing Dynasty images at:

The crescent moon & eight-pointed star item is Islamic— quite possibly Turkish. Compare to the design shown on this "Order of the Turkish Crescent" medal:
