1961P Lincoln Memorial rusted die(s)

[Shleppodella1]

Is this 1961 Lincoln Memorial one of the rusted die(s) that they're referring to in the article "Rusted Dies" on Error-Ref.com and Lincolncentresource.com?
It seems to have all the hallmarks of one. The "rust bumps" are raised NOT inculed which is caused from the pitting/rust on the die making the metal flow into like the design NOT rust on the coin or planchet after strike correct?

[MintErrors]

When coins hit circulation, it's difficult to assess whether it was done in the mint or was in exposed to some abuse after it left the mint.

The rim of this coin is affected. So, more than likely this is not a rusted die, but it may be environmental damage. The rim was placed onto the planchet first, well before the strike. The die is nothing more than a round piece of steel with an incused reverse image of the coin. IF this was a rusted die, it should not have affected the rim.

Yes, the pitting of the die is typically on the design of the working die and it is incused or the pitting ate into the die. The mint workers cleaned off the die the best they could using either elbow grease or even an acid bath solution to clean the die.

Several years ago, Fred Weinberg introduced me to the unique way the US MInt would oil the dies to prevent them from rusting. He sent me a few wax caps. The mint poured the wax over the dies to keep them from rusting after they were oiled. Some looked great as the wax got into most of the working die and created a good seal. I do not know if I have any more of those. I told Fred I would hand them out at shows, and I did. I think he sent me many dozens of them.
