O Cool I have learnt something new today!
I didn't know that dies could rust, well that a mint would actually use a rusted die anyway.
Do modern dies rust too, or I assume that they use better metal or a surface coating on new dies.
Purple penny you so have to write an article on this I want to lean more.
I found this page on the net that describes it a little... Also it says how they use grease on dies -- this explain how you get a strike through grease coin ;)
