When the Proof Silver Eagles went on sale November 19, 2010, the coins carried a household ordering limit of 100. The Mint indicated that this limit would remain in place for at least the first week of sales, after which point it would be re-evaluated and either extended, adjusted, or removed.
Now, two weeks after the start of sales, the limit has been lifted. This might be an indication that sales have slowed and/or the US Mint has sufficient coins available to handle anticipated sales levels through the end of the year and beyond.
From November 19 to 21, the US Mint had reported sales of 273,212 coins. Although this outpaced the prior year, it seemed relatively muted compared to the surge in sales experienced for the 2010 Proof Gold Eagles. Later that week, the US Mint discovered that approximately 2,200 orders for the 2010 Proof Silver Eagles had been deleted in error. They had been contacting impacted customers urging them to resubmit their orders.
Unfortunately, a new sales report has not been made available for the week ending November 28, 2010 to gauge how sales have fared more recently. The US Mint has indicated that they were encountering challenges getting the information and the report would be delayed.
For the time being, the focus of collectors seems to have shifted to the America the Beautiful Silver Bullion Coins, which will go on sale next week.
