A word about toning!
When first minted, silver coins have a bright silvery-white surface.
Over a period of time, and under certain conditions Silver pieces
start exhibiting some very beautiful multi-colored iridescent hues.
Beginners sometimes think that "brilliant is best" but a lot of the time they end up with a dipped or cleaned coin lowering it's value.
Experienced collectors will often prefer attractively TONED coins,
not only do they display a unique look and feel, but?
There have increased assurances that NO cleaning
has hampered with the coins value!
He actually is selling one that made it into a PCGS holder
