Ed Snible has posted a most intriguing discussion of the COINS project, an EU project developing computer software which would allow the tracking of numismatic objects. COINS is an acronym for "Combat On-Line Illegal Numismatic Sales."
In addition to having the potential to track the sale and history of numismatic objects, the software has other applications, such as promoting forgery detection, which Ed discusses.
As I understand it, Ed is a computer guru and knows what he is talking about. I have has also referred to Ed's Celator editorial before, in which he discussed and outlined the potential utility of keeping records of ancient coin sales in seeking solutions to the problem of looting.
For anyone who has an interest in electronic applications to numismatic studies, I recommend his discussion. Read it at "Software from Coins."
