Coin World has a cool article on how the mint prepares the dies for the 5oz ATB pucks...
No hubs, the dies are individually machined. A collector version dies are used for 5-8K coins, the dies for the bullion version are good for 12K coins. Each are struck 3 times, with the force dependent upon the details in the design.

Very interesting... thanks for the link... Cheers, RickO
CCAC members observed this process while the new press was in trial production several years ago. It took a lot of experimentation to attain the present quality for these 3-inch silver products.
Glad they also mentioned the 3 inch medals in this article...
Yeah, they've been putting out some very nice bronze medals lately. The three inchers weigh in at 250g. (8.8 oz.) That's heavier than a hockey puck. Here's my Doolittle from an old thread. (New forum makes it so easy to find one of your old threads.
