that's interesting. They require you to hit their landing page, then one can use that link ... Here's their Report page. The more recent alternative metals ones are near the bottom. The older ones I have to upload it seems. https://www.usmint.gov/about/reports
Some excerpts from various documents from 2012 document 750 coins per minute, that's 12.5 per second for the nickel, dime, quarter and half dollar. DIE LIFE excerpts I believe I read (can't find the page of the thousands of pages I've read) that in one year the Denver mint used over 2,000 obverse dies for that particular year.
Hey, I've never said that Zincolns were a bad choice from the Mint's point of view. If the Mint wants to strike billions of them and then stuff them into warehouses, it's no skin off my nose -- as long as they keep them sealed away from moisture and friction. Circulating them? So stupid that it's nearly criminal. Replacing them with copper-coated steel is about equally stupid; they'd still rot away, but at least they'd be producing rust instead of nasty zinc salts. Aluminum alloy would be more chemically stable, at least, although still terribly vulnerable to acids or bases. (Run one through the laundry and it won't look too good when it comes out.) But they're all fundamentally stupid and misguided, because they're all still one-cent coins, which are laughably trivial in today's economy. Ditch them already.
