  • Where's the Iridium?

    "There is no iridium in the iridium", Kurt Montgomery said to me as we looked over the print out from the EDAX. We were looking at the material analysis of a Waterman's Green #7 nib tip from the 1930's. Most pens today (and in the past) use an alloy of materials for the hard surface tipping on the end of the nib. This alloy is composed of a number of elements.

  • Identifying Fake Gold Bars

    Another good way to test gold and silver coins is the ping test. This is an effective test for 22k gold coins, because 22k coins have a very unique sound. The ping test can be performed while putting the coin on the tip of your forefinger and then softly bang another coin onto it. A real coin will make "piiiiiinnnnngggg" while a tungsten fake will make "clock".
