Haven't looked at platinum, but copper has hit me in the butt. 10 years ago when I worked in it, I could get a coil of 300' of 6 guage copper for $32. 3 months ago it was up to $82. 3 weeks ago it was up to $119. and last week it had gone up to $173. This is just copper. So the prices of platinum must be obscene.
Robert if yopu know of a way to make solid platinum into what you need in a solution form, I have about 2 ounces I could make a deal at the old price to you for.
