Silver Eagles have been minted by the U.S. Mint since 1986. They are a legal tender Silver Dollar--you could if you so desired, spend them for $1.00 each at the grocery store. Each Silver Eagle is 40mm in diameter and consists of one ounce of Pure Silver.  Each year since 1986 the U. S. Mint has issued Silver eagles in both Uncirculated and Proof versions.
What is Uncirculated? Uncirculated simply means a coin that has never been used, that is to say has never been placed into the channels of commerce and therefore has received no wear.  The Mint is a manufacturing plant like any other factory and endeavors to make as many coins of acceptable quality as quickly as they can.  A coin that is uncirculated  can have marks, scratches, fingerprints, stains, etc. all it has to be is unused and therefore not necessarily attractive. All of our silver eagles are taken from original mint tubes and are virtually perfect.  The older dates of silver eagles will have a bit of toning and mellowing as any silver coin that has been out for a while should.
What is Proof?  A Proof coin is not a normal production coin. A proof is the mint's effort to create the perfect presentation piece.  Proof Silver Eagles are struck from specially prepared, highly polished dies and are struck twice to achieve extreme detail with highly mirrored fields and contrasting frosty devices. Each proof silver eagle is placed in a hard plastic capsule , then into a velvet presentation box and finally into a protective box. Take a look at an uncirculated Silver Eagle and a Proof and you will immediately see the difference.
