With the intense pressure leads to high heat, sand will formed crystals, grease may formed  dark green crystallised substances embedded on the field of the coin.

  1. Hi Dickson,
    Very interesting knowledge to us.
    Before seeing these, we always thought they were post mint verdigris.
    Thanks a lot, Dickson :)

  2. Dear whycollect,
    Me too, until l used a 100X magnifying glass (that use to see porcelain wares)to check again.
    I found one of my 1995 50 cents Bunga Raya Series (in BU) were embedded with tiny crystal-like (yellowish green in colour) gem stones on its reverse!

  3. Hi Dickson,
    My goodness, a 100x magnifying glass.
    Haha, you're really great.
    In fact, we used to go to our friend's jewelry shop to see inclusions in gemstones with these equipments.
    Hope these magnifying glass will help you to find more unique specimens.
    Arg, wonder what its like to scan a coin through an electron microscope, haha.
    Thanks a lot for sharing this wonderful idea, Dickson :)

  4. Dear whycollect,
    If l follow your suggestion to scan a coin through an electron microscope,huh!You got to visit me at Tanjung Rambutan already.Siau Liau!haha!!

  5. Hi Dickson,
    That way, probably it may cost more than the coin itself to do it, hahaha!
    But frankly it will be very interesting because every scan that comes out from an electron microscope will definitely look very alien to us.
    Who knows?
    We may even see hairs in our coins, hahaha :D
