1st coin - 35.16 grams, 45.5mm 2nd coin - 27.89 grams, 45mm 3rd coin - 18.80 grams, 44mm A reference, translation, etc would be much appreciated!
First one looks like Xianfeng 20 cash (1850-1861) They can get pretty big, so it might be a coin rather than a charm. I think this matches the type pretty closely. First image is upside-down. Manchurian on reverse is "Boo-fu"
The first one has the Chinese for "20" on it, so I'm assuming it is a 20 Cash of some sort. I don't have my references on me right now. The others look like charms and are not cash coins.
Even though I can't claim to have seen all of the cast Chinese coins ever, certain themes are common on charms and don't show up on official coins. The I Ching hexagrams, for example, I don't think are ever used on real coinage. Likewise the dragon designs on the other. Actual Chinese Imperial Era coins don't tend to have pictures or elaborate designs--just characters (and Manchurian mint marks if they are Qing Dynasty).
