Gus44 New Member Brazil 47 Posts	Posted 03/10/2025 1:07 pm Thanks for the comments! Now, wouldn't it be possible to have DDO with MD on this coin? I tried to take a better picture but the brightness of the coin makes it very difficult, and this is done with a 5 megapixel camera. What I got were these pictures, I focused on the D and the date. The number 1 at the bottom seems to have been damaged again, so it seems that its base is normal. Report this Post to the Staff

IMHO they are specimen coins removed from a set. "Dipping" is not considered cleaning... -from PCGS website Report this Post to the Staff

okiecoiner Pillar of the Community Canada 5397 Posts	Posted 03/11/2025 09:54 am No, it's still mechanical/machine doubling. Read the Wexler link that I pasted above and look at the examples further down in the article. It's still a neat coin, but just an error caused by the locks on the die coming loose and the planchet moves a little (microseconds) as the die rises up and off the planchet. Once the die is locked back in place the doubling stops. Report this Post to the Staff
