PROOF Eagle versus Uncirculated Eagle

A proof coin is a coin struck using a special, high-quality minting process, and made especially for collectors. Modern proof coins often have mirror-like fields and frosted devices, although proof coins struck prior to the mid twentieth century are often distinguished only by their high quality surfaces.

A reverse proof coin is a coin that is struck in the same manner as a normal proof coin, except that the fields are frosty and the raised devices are mirror-like. The term reverse proof does not mean that only the reverse side of the coin is struck in proof finish. The entire coin is in proof finish, with the "reverse" meaning stemming from the fact that the fields are frosty.....

Yearly mintage is unlimited. You can see the various mintage numbers on the right hand column from the above link.

*Note- High global demand in 2008/2009 resulted in a shortage of silver blanks causing the US mint to temporary suspend the launch of Proof Eagles and 2009-W uncirculated Eagles.

Here are some graded slabs in my collection. I will touch on graded coins another time.
