I have
SNG Copenhagen and
SNG von Aulock.
None of them have retrograde
I haven't checked, but GCAM (the former
ISEGRIM) reports the following Cotiaeum Demos/Zeus
types:
SLG
WALCHER 2765
SNG MUENCHEN 24 313-320
SLG
WEBER 7072-4
BMC 17 page 162 #20-24
SNG RIGHETTI 1165
When you cite your coin with retrograde
it is your
choice if you want to say it is a variant or not. You should use the "v" for variant if your coin doesn't match the description in the
catalog, such as having a different abbreviation in the
inscription or a different
monogram or symbol in a
field. If the difference is something that is beneath the notice of the cataloger, such as spacing between letters or more complex drapery on the
bust, you can skip the "v".
