Sap beat me to it and is right again. I really like the one on the right. If they are the size of a US quarter or smaller (usually 23-25mm), then they are 1-cash coins.
@Sap
There are some issues from the 5 Dynasties and 10 Kingdoms period that are arguably struck with wooden dies because their style matches no other cash coin produced previously or thereafter. They are the lead versions of the Qian Heng Zhong Bao, which would make sense since lead is a soft metal. But the fact that cash coins were predominantly cast from antiquity to 1912 makes it likely that these lead issues were also cast.
