Found this 1971 ddo #1 yesterday as well and I lost the 1972 ddo before i could put it in a flip i am so upset but at least i found this gem
The 71' dosent fit into this thread, they may be two different styles of doubling. I am deffering to @desertgem .
It's just an opinion based on photos. Few classic DDO can be done so except the biggies. 55/55(1), 72/72(1). 36/36(1),60/60, sm/lg, DDO, WRPM, etc. Actually, It seems many people can't do 69-S DDO(1) as on ebay. Until 3-D photos and screens are common, they are too flat. Under a binoc scope, you can see the height and surface of the coin. Maybe these on the 72 are more rounded than I see them as flattened. The "L" and "I" in liberty on the 71 is rounded, so no doubt for me there.
No , I was just saying that mainly only the widely separated DD, such as the ones mentioned, can be seen as such by the average photo, such as cell phone, etc. that are usually posted on the forum or ebay. Now some members do take photos expertly , and with good magnification, so they would be the exception. When looking straight at a coin photo, you are seeing a flat image, so it is difficult to tell if the secondary 'doubling' is flat or if it is raised also like the primary image. It may not be the same height, but it will be raised a little if it is a DD. When you look at the coin in hand with a loupe, you can tilt the coin as you observe it and see if the secondary image is flat or at least somewhat raised. I saw the images on the 72 coin you showed as flat rather than as raised, unlike the 1971 coin previously where it was definitely raised. The comments only apply to the classic hubbing and not in my opinion to the newer single squeeze 'DD'. Jim

1972 MDO-001 Designation: MD-1-O-I-CW+II-C (P, D, S, PR) Description: Light spread on LIBERTY, IN GOD WE TRUST and 2 of date Grade: MS63 Population: 1 Markers: This doubling is now considered to be engraving doubling rather than master die doubling. Formerly listed as MD-5-O-I-CW+II-C UVC-2282 DMR-001 MS Reported by: Gerald Landry This is from the Coneca Master Listings. @Johndoe2000$ I was probably Pickin when I said that. The two different types of doubling are very relevant.
