With a 47 million coin mintage, the 2015 American Silver Eagle holds the record for the highest mintage in the series. This high mintage typically renders the issue as generic silver bullion. However, a limited production run at the Philadelphia Mint in 2017 sparked intense interest from numismatic organizations. NGC and Coin World filed FOIA requests to obtain information on these unique coins.
NGC sought to authenticate and grade coins from sealed Monster Boxes of 2015 American Silver Eagles struck in Philadelphia. As these coins carried no mintmark and were visually identical to those from the West Point Mint, NGC had to devise a method to differentiate between the two. By focusing on the Mint’s labeling system, NGC was able to identify characteristics that potentially tied certain boxes to the Philadelphia Mint.
