January is when dealers restock their shelves with the new US coins for the new year. January sales are expected to be 2-3 times higher than a typical month
January 2011 the US Mint sold 6,422,000 one-ounce silver coins mostly to dealers (most ever in a single month)
January 2012, the US Mint only sold 6,107,000 one ounce silver coins mostly to dealers (down from 2011)
The totals for the entire years were
2011 = 39,868,500
2012 = 33,742,500
Total 2012 US mint silver sales were down 6 million ounces less than the bubble peak year of 2011 because of fading demand.
Both January 2012 sales and entire year 2012 were LOWER than 2011 because the fad is fading
If January 2013 sales come in less than 6,107,000 (January 2012 amount) it will mean that the silver fad is continuing to die.
