These are 10 and 20 cash (or wen) coins from China:
10 CASH: about 27 mm diameter
20 CASH: about 31 mm
They carry good numismatic (coin collector) value, especially the 10 cash. The 10 cash in our picture comes from Baldwin's in London. It is in such good condition it sold for a whopping $1600 US dollars during a 2008 auction. Most coins do not reach such high levels. CoinQuest thanks Baldwin's for use of their coin photo.
Very approximate catalog values run like this:
worn: $60 US dollars approximate catalog value
average circulated: $350
well preserved: $500
fully uncirculated: $1000
worn: $5 US dollars approximate catalog value
average circulated: $35
well preserved: $70
fully uncirculated: $150
Note to requester Mike Parma: These coins conform to all the parameters of your request except one, the solid dot between the four characters. Some Chinese coins have such a dot, but we do not know of one that fulfills your other criteria. If you like, use the 'Contact' button at the top of the home page to start an e-mail exchange and we will try to figure out the dot, which could add value to your coin.
