This issue from the latter part of Sulla’s dictatorship has control numbers in two series. One series, like the specimen above, has Roman numerals I-CLXX (Crawford thought this series one went to 169, rather than 170). The other series (illustrated below) has Roman numerals preceded by the letter A and a dot (interpunct). Crawford thought this series had only one die for each control mark like the earlier series and ran as high as CXXVIIII (129). However the Schaefer materials suggest this series only runs to 113 AND most numbers up to 36 are known from two dies.
My working theory at the moment is that they started over at some point a second A series and that were only one A-# die is known for a given number that is equivalent to a missing die in one or the other series.
Why do I care? I’m reviewing all the numbered issues for a talk in Chicago in early June using Schaefer data as a data set that can be used to check and possibly refine of Esty 2011. I’ll release all my spreadsheets/die counts after the paper is delivered and of course the Schaefer images are publicly available and all the ODEC issues are slated for transcription if they’ve not already been done.
ODEC = One Die for Each Control Mark

Liv, the controlnumbers A.xxx do usually have 2 dies/number, but they do run
from A1 to A129 as C stated. I hope I didn’t tell you otherwise.
