American Numismatic Society (ANS)

Denomination Study

This descriptive statistics table is based on data collected from the ANS database.   There is substantial "missing" diameter data in the ANS file and I make no assumption that the information contained therein is correct.   Graphic histograms may be accessed via the "Sample" links and obverse/reverse distributions are available through the denomination link.
