They're not official or anything, I simply got them off of ebay. The left ones (20) I use as 1 cash and the right ones (10) as 5 cash. They both cost me like $3, shipping included. If you're interested, just search ebay for "chinese coins".
Both from eBay ages ago (in fact I only rediscovered them a couple of months ago after finding them stashed in a storage box). I bought them long before I had Loyang with the intention of them being handy for something one day!
The diameters are about one inch, and about 5/8ths inch.
