I'm about 2 years behind on bringing this up but everything just registered. So 
to my question. I remember reading that the choice for silver coins had 2 
reasons. 
1)  precious metal 
2 ) ability to kill pathogens

But how could it kill pathogens if the size of a coin is much bigger than the 
size of the stuff I make.So does the size really have have something to do with 
it?
