Hi Old Bob:

My Grandmother always kept a silver dollar in the milk, and one in the rain 
barrel out by the barn.  Grandma was born in 1897, so she might have been 
considered "old Americana."  Over the years, those silver dollars got pretty 
thin and worn looking.
I have no idea what chemical reaction might have taken place with these old 
silver dollars.  The milk always tasted fresh, with or without refrigeration 
(the milk came straight from the cow in those early days, and not the grocery 
store).

One of the reasons that brought me to this board to begin with, was to try to 
figure out what Grandma knew about silver and keeping milk fresh, along with 
water.  To this day, we add either a silver wire (or now CS) to the milk from 
the store.  We rarely use milk and this prolongs its shelf life significantly.

As kids, when we would get a skinned knee or elbow, grandma would tape a 
silver dollar to the knee or elbow.  Don't know if it actually did any good, 
or made us feel better, but things healed quickly, and I don't ever remember 
getting an infection.
