Starting in 2006, the US Mint began issuing a special collectible version of the American Silver Eagle. These coins were struck on specially burnished blanks and carry the "W" mint mark. Mintages for these coins are generally much lower than the comparative bullion mintages.
The 2006 coin was also included in special 20th Anniversary Sets. The 2007 coin was included in a special Annual Uncirculated Dollar Set.
The table below shows approximate mintage data from 2006 to present. This information is based on sales data. Official data is not yet available.
