    Saw this on PM bug, looks neat if it works.

    iPhone app for ping test gold/silver coins

    --------------------------------------------------------------------------------

    Maybe some of you would be interested in my new project of an iPhone (iPad) app for testing gold/silver coins. In this moment my app can test 1oz Krugerrand and 1oz silver Maple Leaf.

    I have a few free promo codes to share with you. Let me know on Private Message that you are willing to test the CoinTrust app.

    Here is a short tutorial movie how it works:

    Before watching the tutorial, I was expecting a picture of each coin with pictures of the actual size and thickness. This would allow you to place the coin on the phone to measure it.

    I'll buy the app if someone sends me a gold coin to test.

    I installed Bullion Test (free version) to an Android cell phone. It worked for a Silver Eagle just right. It also shows the measured frequencies, which may be interesting.

    I used this method to ping test the coin: I used a sharp knife to cut a worn end off an eraser. I used that little piece of rubber to support the coin beneath and then I knocked the coin with a wooden pencil.

    Clean the coin.....
    Fine for bullion.
    Looks like too many variables on testing have to be just right.
    Table type & thickness, distance & position.
    Ok at home after the deal is done, but not so much for a coin buy FTF at McDonalds.

    A Silver Eagle vibrates nicely. I have been told that gold-plated tungsten coins do not vibrate. They sound dead in a ping test. I also tested a two Euro coin, which is made of two concentric pieces of different metals and sounds dead as well.

    All sound money sounds right. http://www.gold-eagle.com/article/sound-money-and-ring-truth

    Having the coin flat on a finger tip works just as flawlessly.

    Perhaps a Fisch Ringer tool would be a helpful toy.
