I suppose I learned enough here to know that this is that flat, shelf-like mechanical doubling, but I've never seen it quite as extreme. Can somebody please explain, from a physics standpoint, let's call it, just how this happens? The die had to strike this little bugger twice, right? Quite honestly, I read a lot, from the laconic to the fancy-schmancy explanations, and I still don't understand it.
Thanks, Mike. So this is the end of the life of the die, the point at which they change it? In fact, let me edit and add, they may have even polished this die already, if the striations (if you can make them out) near the motto, along the edges of the wings, and lower-right are evidence of that. Looks like they used a brillo pad D), but it does look harshly scratched/rubbed.
Mike, Having been a CT member for a few years now I know that your responses are highly respected. I am not an error coin collector per say, my passions are proof sets and BU years sets 1964 and older. I do however treasure my BU 1955 Bugs Bunny, mostly because it was minted the year my lovely wife was born. Would you please elaborate on what the major or definitive sign of this condition are. With Great Appreciation, Allen
I see lots of radial flow lines and orange-peel surface, all of which are signs of advanced die wear. But, I wouldn't be surprised if there were die scratches as well. This die was well past its useful life, but 1983 was a banner year for decrepit, overused dies. Die deterioration doubling often takes the form of a halo or outline around the affected design elements.
If I had my camera at the time instead of just my scanner you'd see for yourself in clearer focus/detail you're exactly right, the way you articulate this is exactly how it looks. Thanks again.
Appreciate it, Mike. Very instructive glimpse into this strange little world, too, if I might call it that. Didn't really know what to make of some of my lettering that was "doubled" on both sides (never understood "mechanical doubling" to manifest like that, but I didn't know what else to call it). But now I know...
Mike: Thanks for the reference, I have wondered about some early Jeff's that looked like that. And thanks for starting this thread.
