2014-2017 Bullion Silver Eagles Can Now Carry “Mint Marks!”

NGC and PCGS can now designate certain 2014-2017 American Silver Eagles with their Mint location! Find out how more about this recent development and how to add this detail to your collection from ModernCoinMart.

Update as of February 2020- Struck at Silver Eagles Continue

The tradition has continued ever since the first discovery of “Struck at Silver Eagles” in 2017. We have select 2020 dated bullion American Silver Eagles that were “struck at the West Point Mint,” but that do not carry its “W” mint mark. The experts at Numismatic Guaranty Corporation (NGC) have been able to certify which bullion issues were struck at the West Point Mint and proudly display this information by placing the “W” Mint mark in parentheses on the certification label. Be sure to check out our assortment of 2020 Struck at Silver Eagles and keep reading to learn more about this discovery.

In the early 2,000s, the production of American Silver Eagle bullion coins took place exclusively at the West Point Mint. However, in response to the record demand for these U.S. silver bullion coins, the U.S. Mint decided to supplement their annual production by minting additional coins at their San Francisco facility in 2011.

Although these coins did not bear Mint marks on them, their Mint location is still known thanks to information provided on their packaging. Until 2014, when this information was removed, each nylon strap used by the San Francisco Mint to seal their 500-coin Silver Eagle “monster boxes” had the Mint location printed on it!

 The Numismatic Guaranty Corporation (NGC) and the Professional Coin Grading Service (PCGS) have taken advantage of this information by adding a “Mint mark” of their own to their labels. Only available for these San Francisco-struck Silver Eagles, this mark consists of the Mint location, “S,” in parentheses directly after the date. The parentheses are there to show that while the Mint location is known, there is no physical Mint mark on the coin.

In 2015, the Mint again began to supplement American Silver Eagle production with additional coins from the Philadelphia Mint. This happened during the transition period from one year to the next, since demand tends to be highest at the start of a new year. However, these coins struck at Philadelphia were still sealed in monster boxes that said “West Point Mint,” or “WPM” on their straps, making it impossible to know where coins inside were actually produced.

Collectors have long suspected that the U.S. Mint was striking bullion Silver Eagles at multiple Mints, but besides the 2011-2014 (S) issues, there was no real evidence. Then, in early 2017, the U.S. Mint finally revealed that the bullion coins were, in fact, struck at three different Mints. While no additional details were given, this was that was just what was needed to push the numismatic community to take action.

Coin World magazine’s Paul Gilkes quickly responded to this new information from the U.S. Mint with a request for a specific breakdown of mintages by Mint facility for recent Silver Eagle production. The Mint refused to provide that information, so Coin World filed a Freedom of Information Act (FOIA) request on February 6, 2017.

Meanwhile, NGC had started to notice a difference in the quality of 2017 American Silver Eagles that suggested the coins were made at different facilities. They believed the coins with the highest quality came from West Point, which uses robots to place coins in tubes, while the Philadelphia and San Francisco Mints manually tube their coins, providing more opportunity for damage.

Additionally, officials at NGC began to notice a pattern in the serial numbers found on the straps of Silver Eagle monster boxes. They believed these different patterns could be the result of production from different Mints, serving as yet another reason to suspect Silver Eagles were struck at multiple locations. They inquired with the U.S. Mint about these inconsistencies, as well as filing a FOIA request of their own.

The U.S. Mint confirmed that their West Point facility is equipped with robots to tube coins, but stated it also uses manual tubing, while the other two Mint facilities use manual tubing exclusively. In response to the FOIA requests, the Mint on March 20 of 2017 provided a breakdown of which Mint facility produced how many coins for the years 2014 to 2017:

  • 2014: 23,450,000
  • 2015: 49,920,500
  • 2016: 31,900,000
  • 2017: 5,425,000*
  • 2014: No Coins
  • 2015: 79,640
  • 2016: 1,151,500
  • 2017: 1,000,000*
  • 2014: 7,025,000
  • 2015: No Coins
  • 2016: 4,650,000
  • 2017: 3,000,000*

For the entire period in question (2014-2017), we now know that almost 17 million coins were struck at the Philadelphia and San Francisco Mints, while production at West Point was almost 108 million coins. The U.S. Mint also confirmed that NGC was correct about the numbers on boxes and provided a breakdown of the numbering system for serial numbers on monster boxes.

 Various six-digit serial numbers starting with “1,” “2” or “3,” or a five-digit serial number beginning with the prefix “WP.”

  • 2015: Various five-digit numbers starting with “1.”
  • 2016 and 2017: Six-digit numbers starting with “5” appear on boxes.
  • 2014: Red-colored straps were used on the boxes.
  • 2016 and 2017: Various six-digit serial numbers starting with “4” appear on boxes. 

On Mar 31, NGC announced in a press release that it “can conclusively identify the Mint facility that struck the coins contained in each 2011 to 2017 monster box.” On April 5, PCGS announced that “it will attribute certain 2014 through 2017 American Silver Eagles with a “Mint mark,” indicating where the coin was struck.”

Thanks to the information provided by the Mint in response to the FOIA requests from Coin World and NGC, collectors are now able to collect these coins based on where they were produced.  As a result, this segment of the market has exploded in recent weeks with graded coins, especially the key-date 2015-(P) with an ultra-low mintage of only 79,640 coins, continuing to increase in value. That coin is the lowest mintage bullion coin of this type ever produced.

MCM will be offering this key 2015-(P) issue, along with a broad selection of other American Silver Eagle bullion coins from 2015-2017. All of these coins that have grading labels from NGC indicate where they were produced at, as well as condition and other information. Some options even include special labels bearing a colorful theme representing the Mint’s location.
