Hey Coop, I noticed you took the images for this coin on Coppercoins, so I didn't know if you had the plate coin or just took the images. If you have it and have some free time, can you take a look and see if the tilted clash is present below Lincoln's bust please? Below is my observation of an example I own. I posted this at LCF and just copied it here.
"1960D-1MM-107 (RPM-107) (WRPM-095) should cross reference to ADC-1c-1960D-048(SD).
http://www.coppercoins.com/lincoln/...ie_state=ldshttp://www.maddieclashes.com/2680-2/I discovered this while working on my spreadsheet of varieties. I got this coin as a bonus in a group I won on
ebay in June 2016. John (LCF member Chugly) was the seller, so I hope he sees this thread and can check his others at some point. Who knows, we may could pin point at what stage the tilted clash occurred. Anyway, I was checking the attribution to get the die state and die marriage, if applicable, and it matched CC's LDS perfectly. I always check the small dates for a tilted clash, and sure enough, the top of STATES is below the bust. I looked back at CC and the clash was not mentioned as a die marker. However, if I wasn't intentionally looking for it I would not have noticed it. I checked VV and the example there is a much earlier die state (stage B). I went back to the coin and studied it well for additional clash marks, but could not find any. I started down the list on MDC looking at the listings with clash position 3/ only and didn't have to go far. The die gouge under the 1 on Lincoln's bust jumped out in the first image. The diagonal scratch between the 1 & 9 match CC's, and my coin has the dents above RI on the reverse. MDC doesn't mention the RPM, but at this die state it is extremely hard to see unless the angle is perfect. The shadow on the east of the D in MDC's image of the date would hide it easily. I ran out of time the other night and never got around to taking pics, but I think CC & MDC will do just fine. The images are better than any I could take anyway, lol!
Sorry this was so long, but I wanted to take you through my process. I would love to hear your thoughts/comments. Also, I am going to reach out to Coop through Coin Community Forum since I noticed he took the images for CC. He may have the plate coin. I'll update if I get any new info.
