IGT is using colorization to save money on the strikes, be they the $200 or $40. Why don't they just lower the silver content. There is nothing that says they have to use .999 silver, only that they mark or label the silver that they do use, if they label it. They could use sterling silver or a lower grade of silver and keep or lower the price of all silver strikes to the casinos. Just one persons view. Hope IGT reads this post.
