So...it appears archies don't mind exchanging artifacts for money. I'll let you decide whether that flies in the face of the very thing they accuse treasure hunters of doing...
"When Fiorini learned that the Archeological Superintendence, a government office that oversees heritage projects, in Cagliari did not have enough funds to retrieve all the ingots, he convinced INFN managers to contribute 300 million lira (US$210,000) to the operation, which was completed in 1991. In exchange, a proportion of the recovered lead would become available for physicists."

However, she says she is happy with the collaboration, because physicists are performing important analyses on the lead."[/FONT]
