These security features will be: 1) visible to the average person with an untrained eye 2) visible to numismatists, bullion buyers, and anyone who knows what they're looking for (under a loop?) 3) a third layer of security for Secret Service and Mint personnel to authenticate the ASE. This reminds me of the Royal Canadian Mint's DNA system which I explained in the past: https://www.cointalk.com/threads/royal-canadian-mint-bullion-dna-system.316724/ Secondly, it sounds like this will result in an overall redesign for the coin. Personally, I am very excited about this. I have been a Silver and Gold Maple Leaf buyer due to their anticounterfeit measures, even though I am an American. If the Eagle is redesigned to feature several anticounterfeiting measures, I might just become an American silver convert!
