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.While specimens of this larger issue weighing over and under 12 grams probably date to the same period, many collectors value the heavier specimens more highly. Specimens over 12 grams exist and command a premium price, but they are rare.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.It seems likely the Ch'in government would have had a method of determining the mint and period of issue of any given coin, as such systems appear to have been in place on other coins for over 100 years.No mint marks occur on these coins, but it is unreasonable to assume all were cast at a single mint.Ch'in existed as a feudal state under the Zhou since before 1000 BC, casting coins (currently listed under Zhou) from about 400 BC.
’, and brings up the very point it seeks to avoid.” Controversy is raging in Australia over changing the national curriculum to reflect the new BCE orthodoxy.
Having examined a number of Pan Liang hoards, we found most specimens within a single hoard will be of uniform diameter but the weight can vary significantly.
This had lead us to believe the coins diameter is the important factor in determining the period or issue.
Locally, the regnal years of kings were often used.
The Julian calendar was a system of fixing the number of days in each month. The most popular system was the AUC system used throughout the Roman Empire. I agree that regnal years was probably the most common type of system but AUC was much more widely used.
