Over the last few decades several methods have been used to harden working dies to extend their life
One of those methods included nickel plating, and for some years, the Royal Australian Mint used this method.
The resultant business strike coins struck from those dies appeared to be proof, except that the whole coin appeared to be struck from the 'polished' die, not just the fields, as with modern proof coins.
The US Mint may have nickel plated their working dies, but when this may have happened or not, I cannot provide further knowledge.
