A MASTER HUB MYSTERY

Something vanished from the United States Mint sometime between 2008 and 2022. No announcement was made. No one seems to have noticed.

After almost 15 mins of reading, and still not done, I think that the article is way too long.

 

I am so sorry! Unfortunately, I did not write it considering attention spans! I will summarize for you: Implications are that Master Hubs are no longer a part of the die making process. If that is true, any attributions of Master Die Doubling that assume Hub Doubling are inaccurate.

 

The Mint is now moving beyond CNC milled Master Dies to Laser Engraved Master Dies. The 2024 American Liberty silver medals and the 2025 American Liberty gold coins (resurrecting the 1794-dollar designs) are the first to incorporate this technology. The 2025 Laser Engraved American Eagle One Ounce Silver Proof Coin is the first American Eagle Silver Proof Coin (with a laser-engraved privy mark) minted using laser-engraved master dies.
