Archie - Even with silver at the 8.05 you state IGT or Global or Sunshine aren't loosing money yet given the fact there is still only about .66 of an oz. of silver in each strike. I would bet that alll the companys have a large stockpile of silver that was purchased at much lower prices.
I would also say that if silver continues to go up in price we would see a reduction of the amount of silver in a strike but the strike program should continue.
As to the colorized $200 strikes if collectors bocott these it could lead to the $200 going away again.
May thoughts only
