It is a lot more likely that it is Die Deterioration. I can't fully tell from the photos because of the flash and glare. The MM has the same doubling as the rest of the coin. This is usually a guarantee that the coin has worthless doubling. But for the purposes of identifying it. One would need to reference the Denver MM DDO's not the Philly's @R_rabbit
Imho, my mistake, sorry. I believe this is the link I should have sent. http://www.varietyvista.com/01b LC Doubled Dies Vol 2/1984DDDO001.htm
That picture is of the 10th memorial bay to see the known markings of 1984d-1DO-001 not saying that those are def the markings just saying they could possibly be.
