Year To Date Mintage By Month For 1 Oz Gold And Silver American Eagles.

The available weekly production of Silver Eagles are being allocated to the buyers from the US Mint presumably because the Mint cannot produce as many as the demand from the buyers would indicate. Year to date (through April 23, 2013), Silver Eagle production and sales are up 50% over the four months through April 2012.
