Well, I am very sorry to have stepped onto someones toes with my remarks and I do apologize to all who feel offended. I admit, English is not my first language. However I suggest mmissinglink to clam, relax and chill a bit. Aureus, who's obviously intelligent and understood my sarcasm, is not to be blamed for anything just because he sided with me. mmissinglink, I do not need to be schooled on what the definition of contamination is.

Perhaps let me rephrase my point of view a bit.
I understand Silver is, among others, precious, rare, difficult to obtain, (relatively spoken) is not really cheap and needs some process to be refined. Some nasty chemicals and some substantial energy and demanding electro-chemical process is involved in refining. So at the end of the day one obtains a 99.99% pure and precious element. Lets say it is been formed into a coin of some sort with some design. Now, at this point with the application of color, paint, ink, which to my knowledge, is neither precious nor noble nor in short supply, the former 99.99% pure material is now been CONTAMINATED with a foreign none precious material. (e.g. greasy fingerprint)
A material that very well was just removed during the prior refining process. So why on earth would one want to reduce the purity again is beyond me. Because it looks good, sells well ? OK.
Gold Guilding a silver coin, adding rare gem stones at least adds preciousness to it. Paint not so much, at least in my books. Let alone some coloration look so ugly cheap that to me is a total turn off.
Anyway please, let us put this ranting to rest and move on.
