Please read Cultural Property Observer and comment on the Libyan MOU. If the MOU is completed and includes coins it will become difficult for Americans to buy ancient coins from Kyrene in European auctions.

I stumbled across this 9 minute video which shows the process of creating a medallion with realistic bust using a CNC machine. The medallion produced looks quite good! It looks better than most of the 'coins' featured in do-it-yourself coin making videos. Show More Summary

ISEGRIM is a database of 60,000 Greek coins of Asia Minor developed by Otfried v. Vacano at the University in Düsseldorf. There are no pictures. Unlike other search sites, instead of filling out forms the user was to write "queries" using a special syntax similar to Lucene. Show More Summary

The Institute of Archaeology of the University of Warsaw has provided a remarkable 3d scan of a Kushan bronze coin. The model was done by Otto Bagi and Sergi Mañas Jolis. Apparently photogrammetry was used to to infer the 3D coordinates. Show More Summary

I purchased this coin in 2004 from Clark's Ancients. It had been identified as being from Abdera, like the first example on this CoinTalk thread. It did not look like that type.

My web site snible.org is down. I hope to have it up again tonight. Until then, you may access the AWS mirror. It was not hacked. The operators shut it down because it went over quota. It is apparently under attack by a virus.

A very unusual reverse on an ancient Greek diobol! The reverse side literally depicts the lion's tail end. Typically on ancient Greek coins it is the front half of the animal that appears. The front half is called a 'protome'. There is no word for the back half appearing, as there hasn't been a need. Show More Summary
