Metrological analysis
« on: March 27, 2020, 09:24:23 AM »
Elsewhere, I am reporting on developments in the field of metal analysis. To put those further into perspective, here is a study that does without metal analysis. It is for you to decide if metal analysis would have enhanced the conclusions.


A Metrological Survey of Ptolemaic Bronze Coins, by Daniel Wolf, Journal of the American Numismatic Society - 2013, 2014.

Analysis of many Ptolemaic bronze coins clarified relationships between their weights and values during the reigns of Ptolemy I–IV. Two aggregate bronze weight standards came to light for time periods before and after a coinage reform c. 265–260 BC. Analyses of the new empirical data showed that previous theoretical Ptolemaic bronze weight standards were incorrect. Large samples gave more confident estimates for the weight standards, the relationship between them, and the value structures of denomination series. Te data also revealed some previously unrecognized denominations. The analyses provided reliable mean weight values for many coin types to replace conflated approximations found in preceding literature. Statistical and graphical comparisons of data for individual types and value series showed that post-reform minting technology permitted weight-to-value relationships that were highly conserved and faithfully executed for half a century at Alexandria and provincial mints.
An unidentified coin is a piece of metal. An identified coin is a piece of history.
