Fathers Coins From China

None of these are technically "Ancient", though you do have one that certainly qualifies as "mediaeval": coin #3 is a Tang Dynasty "Kai Yuan tong bao" cash coin, struck sometime in the period from AD 621 to AD 907. Unfortunately, because they were issued for such a long time - the Kai Yuan coin still holds the record for longest ever unchanged coinage design - they are still quite common, and therefore not particularly valuable.

All of the coins without holes in them are relatively modern, early 20th century. Some were made under the Empire (pre-1912), some under the Republic (post 1912). The coins with a dragon on them are all Imperial issues. None of them actually bear a date, except for coin #5, which is dated using the Chinese Cyclical Calendar to the equivalent of AD 1906. These are all ten-cash coins. Theoretically, there were 1000 cash to the dollar, making 10 cash equal to 1 cent. In practice, the exchange rate varied between 1000 and 3000 cash to the dollar, and the coins of some provinces were rated at lower value than others.

Coin #2, the other cash coin, dates from the Dao Guang emperor (1821-1850).
