Show me your Coins made from Rusty Dies

What I am talking about are pitting or roughness raised area's appearing on the coin that are the result of dies due to rust. Because of the hardness of the die steel treated with heat (annealed) to relax the molecular structure of the alloy, rust can be on the die and tho they polish the die some rust may be missed causing raised area's on the coin.
Prepared dies which were stored without adequate greasing will rust.

I find older coin years, worn dies and softer metal to have this effect more often.

In my opinion a coin struck from rusty dies is absolutely a genuine mint made effect, the same as a die break, die chip, die crack, cud, or clash. Most collector do not collect these but I find them fascinating. Ed

I want to point out that not every grainy looking surface or bubbling of the coin's surface is from a rusted or pitted die. Please due some research to find out for sure.
