We previously discussed the possibility that some Square-Foot Spades and early Square-Holed Round Coins were cast under the Ch'in, but we also believe the earliest Pan Liang were cast before 221 BC.
This series is difficult to classify, with specimens occurring at weights from 2 to 18 grams (but rarely over 12 grams), and diameters from 14 to over 34 mm.The Western Han dynasty does not actually begin until Liu-peng arose the victor, declaring himself Emperor of Han in BC 202.No specific coins can be assigned to this period and it is likely a coinage based on the Ch'in types would have been continued.With the exception of some very late issues (Han period), none have inner or outer rims.They appear to have been cast in reusable carved stone (steatite) molds, several of which still exist today.While the AVERAGE weight of an issue is closely tied to the diameter, the weights of individual specimens can vary so much (up to 200%) as to be almost meaningless (see our earlier discussion of weights).
Unfortunately, not enough dateable hoard or archeological evidence currently exists to work out the exact classification of the Pan Liang series, but the Records of Han provide a clue, stating that heavy Pan Liang were cast until about 187 BC.
Ch'in existed as a feudal state under the Zhou since before 1000 BC, casting coins (currently listed under Zhou) from about 400 BC.
Traditionally we refer to the Ch'in Dynasty as beginning in 255 BC when the Ch'in conquered the Zhou.
It is commonly accepted that in 221 BC, at the time of the unification, Ch'in introduced the Pan (pronounced "Ban") Liang coinage, discontinuing knife and spade coinage.
This is by no means certain and we find it difficult to accept, believing the coinage of this period is more complex and knife and spade coinage was phased out gradually.
This takes us back to our earlier theory that square-foot spades, and possibly ming knifes, were still in use throughout much of the Ch'in period, and may in fact have been the principle coinage of Ch'in. It is likely that the 34 mm Pan Liang coins are the earliest issues and may date to the period when the Chin Dynasty was a sub-dynasty under the Zhou. Collectors prize the heavier specimens, so the weight does affect the value in the market, but when these coins were in use it probably was not a factor in their circulating values.
