3NVTEs Posted April 26, 2009 Report Share Posted April 26, 2009 Hello again! Here's one that has blisters and slightly burnt raised images. However, the tripling(is it?) still well-defined and visible to naked eye. All the other Obverse and Reverse elements have spreads and separtions. Is this genuine DD? Thanks again! 3NVTEs Link to comment Share on other sites More sharing options...
Steven_2b1ask1 Posted April 26, 2009 Report Share Posted April 26, 2009 Appears to be a severe problem with the plating bubbling, die wear and damage to the devices. Appears to have some of the plating sheared from the coin. Don't see any doubling. Just my opinion. Steven Link to comment Share on other sites More sharing options...

Thanks again! 3NVTEs Agreeing with the Steven's statement in that this appears to be machine doubling, hub doubling or die chatter, all of which are called machine doubling. The 2nd or doubled partial design is flat and not of the same height as the other full image design. The bottom layer is most likely, as previously stated, surface metal movement. A true DD will have 2 complete sets of the same design and be approximately of the same height, whereas the MD will be flat as it appears in your pics. My humble opinion for your coin. The descriptions given above are for those who may not know the differences between DD (double die) and MD (machine doubling) on coins, medals, etc & not to offend anyone's intelligence. A really good book with excellent pictures is "The Error Coin Encyclopedia" by Arnold Margolis. I have no affiliation with any references I suggest.
