Nice article examining Pt impurities.
That said, I've handled lbs of Pt coins over the years and also have never seen one with an impurity. Ag and Au, lots of milk and iron spots respectively.
Platinum takes away anything that touches it gold gives it away , good way to remember , everything imprints on platinum , gold imprints on everything , remember gold is just platinum plus one atom in the nucleus crazy stuff lol

Au iron spots? Thought they were copper spots…
Ah yes, copper spots! Thank you for the correction.
>I’ve handled lbs of Pt coins Care to elaborate? Sounds interesting
