For anyone looking for cheap silver, here is an easy and FREE way to do it, that does NOT involve standing in cold water in a river-
In 1965, the US pulled the 90% silver coins. HOWEVER- from 1965 to 1970, the half dollars were STILL 40% silver. At today's rate, each has $4.01 worth of silver in them- and they still circulate.
Take $100, Go to banks or credit unions, ask if they have rolls of half dollars. Take them home. Set up a table where light is good. Crack open your favorite adult beverage.
Carefully remove coins from wrapper, preserving wrapper. Go thru coins- you may get one every few rolls. If they are 1971 or later, restore them to their wrappers. Return the 1971 and later rolls to a different bank. Repeat as needed.
They ARE getting more scarce, but are out there. My big score was one entire roll of 1964 Kennedy halves. Silver value is $9.82 each.
