The hoard, comprised of 108 gold coins, mostly dinars dated to the Fatimid Period (ca. 900 to 1100 AD), was discovered in a pot by a university student. The coins bear the names of sultans and blessings, and usually include a date and a mint name that indicates where a coin was struck. http://phys.org/news262525924.html Other Sciences Thu, 26 Jul 2012 12:52:24 EST news262525924 Archaeologists and engineers from the University of Southampton are collaborating with the British Museum to examine buried Roman coins using the latest X-ray imaging technology. http://phys.org/news261138174.html Other Sciences Tue, 10 Jul 2012 11:23:09 EST news261138174 Dr. Ronald Kohser has been keeping a close watch on coins during his career. According to Kohser, a professor of metallurgical engineering at Missouri University of Science and Technology, it currently costs the U.S. Mint about 1.7 cents to make a penny and around 7 or 8 cents to make a nickel. The amounts include metal content, tools and dies, and labor. http://phys.org/news250851310.html Other Sciences Tue, 13 Mar 2012 09:56:02 EST news250851310 Israeli archaeologists have uncovered ancient coins near the Western Wall in Jerusalem's Old City which challenge the assumption that all of the walls of the Second Temple were built by King Herod. http://phys.org/news241285233.html Other Sciences Wed, 23 Nov 2011 15:40:46 EST news241285233 (PhysOrg.com) -- Using a new coupled mass spectrometry technique that employs multiple collectors, researchers in France have shown that it was not an influx of silver from the America's that caused high inflation in Europe from the early 1500's to mid 1600, as some historians have long believed. Their results, published in the Proceedings of the National Academy of Sciences (PNAS) show that the gradual replacement of coins made from Spanish silver to imported Mexican silver, did not occur until nearly fifty years later. http://phys.org/news225715623.html Chemistry Fri, 27 May 2011 12:20:01 EST news225715623 A huge number of students ranging from linguists to those studying coins and family ancestry are benefiting from a 100 year project to compile the world’s most comprehensive dictionary of Medieval Latin. http://phys.org/news224426072.html Other Sciences Thu, 12 May 2011 13:34:44 EST news224426072 Buried hoards are the stuff of childhood dreams.
