Hello!
This is fascinating. The coin pictured on the title page is from the
Sunrise Collection, and it can be seen on page 73 of the book. The book lists it as coming from an "uncertain location" and being unpublished. It matches the
style and size criteria of the other coins, so obviously there has been a considerable amount of information discovered about this
type since "Numismatic Art of
Persia: the
Sunrise Collection" was published. Do you know when and how these coins were discovered? Also, could it be possible (since the coins are from
Baktria) that the present coins were struck under Bessos, the
Baktrian satrap-turned-usurper of Darius III?
Thanks,
TPG
