Somewhere on this planet shouldn't there be coins with the rust stamped right into the metal?
So the early 1900's mint worker shows up for work Monday morning and sits at his coin press. 
He dons all his safety gear, (back then there probably wasn't any) hits the press's green "ON" button, then sits down to take a sip of his piping hot coffee from a tin mug. 
Suddenly he spits it out realizing he never checked the dies and slaps the red "OFF" button. 
Everything looks good. Right dies and they're nice and shiny (at least NOW they are). Back to ON and the coffee. 
Shouldn't there be a few coins in the hopper with the rust impregnated right into them? If so why haven't we found any?
Great transactions with oih82w8, JasonGaming, Moose1913.

maybe the rust just falls away after a time?
Thanks Barndog, Now I know what seriously rust dies do.
That's really a pretty extreme example. Thanks for posting Barndog.

This dime was struck with a rusty obverse die.
Coins struck from dies that had actually rusted are unusual. Most of what has been called "rust" can be attributed to spalling, and various other metal fatigue/ crystal failure reasons. For a recent article see the SLCC journal (Craig Sholley, John Dannreuther) discussing hydrogen embrittlement and related problems.
There are a few notable varieties of large cent that display rusty dies. The S-157 being the first the comes to mind.
That's the Dan Holmes S-157 LDS state IV,
with both dies with heavy rust. AU-50.
You should show the rev.
