2% platinum to keep the gold fresh looking?! I can see a little
cache from the Pt and an effect on the color. I'd be surprised to
find out the platinum is really doing anything for the "fresh" look.
I would expect the metal to be darn hard from stamping, and unwieldy
for stamping without the Pt which would be a great grain refiner.
Sounds to me like a cool alloy with an odd marketing angle. Platinum
is a powerful lightener of color in gold. Unique color for sure.
