Good call, Roublizer!
Looking through Krause World Coins I see that the two coins in the upper right with busts, dated 1335 (1916) and 1337 (1918), are Sultan Ahmad Shah of Iran. Photos of other sides, weights and diameters are needed for further attribution.
The coin that has been made into jewelry is Iran, Nasir al-Din Shah (1848-1896), not sure of denomination without weight. It would have had some numismatic value before being made into jewelry, but now probably bullion value. The others have book values slightly above melt (maybe 10%) but realistically most coins sell below book value so I would value all these coins at bullion.
(the remainder of this post uses diameter info provided in a private message)
The 22 mm coin is Turkey 100 Kurush (not 50 Kurush as I had previously guessed above), AH 1327, KM 800, and personally I would grade it about XF. It contains 7.216 g of .9170 gold, current melt value $303.
Without weights, the other attributions are tentative (could be other denominations that look similar, and you'll need to weigh for accurate valuations). But here's my best guess for a couple of them.
The 18 mm appears to be Iran one toman AH 1335 (1916), KM 1074, weight 2.8744 g of .900 gold (so 2.587 g gold at today's price of $45.79/g = $118 melt value if I am correct about the weight). I would grade it VF.
The 14 mm coin appears to be Iran 5000 dinar (½ toman), AH 1337 (AD 1918), KM 1071, 1.4372 g of .900 gold, which I would grade XF. Today's melt value $60 if I am correct about the weight.
