Im trying to get better with identifying machine doubling. For some reason, I just cant wrap my head around it as a "part timer". I got this 1971 half dollar at Publix a few weeks back and decided to take a look at it today. I see all kinds of machine doubling on both sides of this thing. This is all machine doubling correct?
In the 70s , a doubled die would have numbers , letters, devices, close to the same height as the first hubbing numbers, letters, and devices, even if it was a minor difference, a notch would occur or something to indicate it was doubled. A true DD , produced by the multiple hubbing process, compared to the single hubbing of modern coins increased the width/thickness of the numbers, letters, devices etc. The single hubbing "doubledies" decreases the normal width as it smears some of the metal away from it. BUT the "experts" decided they are doubled die coins anyway, Jim
A misaligned die (MAD) is when the die is placed to one side or the other in the striking mechanism. You will notice less "edge" on one side and an increased "edge" on the other side (180 degrees away - same side) but the flip side will be aligned. On your coin, notice the increased edge at the 19 and the decreased edge at the R in Liberty. No added value, just an interesting observation.
M.A.D. Nice MD you have there. It doesn't get any respect but still fun to see for us beginners. Check out my avatar.
