Minutes 01.03.13

The meeting was called to order by Christian.  Sixteen members were present. The reading of the minutes were dispensed with per popular vote.

Old business: We are looking to purchase a projector in the next month.  It appears that Fry's has the best available models at the best prices.  All members agreed to allow Christian will make the purchase.

New business:  We were unable to reserve the library room for our July meeting.  Since the first Thursday of July is Independence Day, we discussed either having the meeting elsewhere or possibly hosting it on a different day since many will be enjoying time with their families.  After the meeting, Christian confirmed that the library room will be available on Tuesday, July 2nd.  We will make the reservation and discuss with the members at our February meeting.

Program: Kurt Baty joined us to impart his knowledge of elements used in coining.  His slideshow presentation included the following:

  • Kurt provided us with a table of the elements and indicated which elements had been made into coins - either for currency, commemorative or (in some cases) for fun.  He was kind enough to allow us to post a copy.  See below.
  • Nickles are actually only 25% nickel and are 75% copper.
  • First pure copper coins U.S. 1792 Coin Act.
  • Gallium will melt – not good for coins.
  • Niobium – colorful coins by anodizing it. Austria’s 2003 euro has a blue core with a silver outer ring.
  • The first coins made for currency were silver coins made in Athens, Greece around 400 B.C. Before this people bartered.
  • Tin – First specimen British King James II halfpenny 1685. Few survived.
  • Some coins made of Rare Earth elements do exist, but are encapsulated as they can be radioactive or toxic.
  • Tungsten is the hardest pure metal. Most coins are struck using a 100 ton press. To produce coins of tungsten, a 300 ton press was used but broke after making only three coins.
  • Platinum – First platinum coin struck was a British 1825 platinum mule pattern piece. The obverse and reverse are from different coins on a pattern piece. The obverse showed an 1812 Pattern 9 Pence Bank Token and the reverse is a 1825 Farthing.
  • The Kingdon of Lydia, Sardes (time of Croesus) made first coins made of pure gold and pure silver. These were made around 675 B.C.
  • Bismuth is the last stable element at 83.
  • Elements on the chart in red are radioactive.
