Dowhat Pillar of the Community United States 876 Posts	Posted 02/26/2022 1:52 pm I am not to familiar with the die events that may occur on these coins. As far as I can tell, these are dies way past their age. If I am not mistaken, DDD does apply to single squeeze working dies. I am not clear on this. I am noticing ray like lines that seem to emanate from the center to the rim. The outer devices are extremely diminished. I think these dies are dead. One might be fooled into thinking some of the outer devices are doubled. No way, right? Old dies? I am just inquiring as to what this is called. Terminology. Report this Post to the Staff

JimmyD Bedrock of the Community Canada 21589 Posts	Posted 02/26/2022 2:20 pm You have one D too many, it is just called Die Deterioration. DDD stands for Die Deterioration Doubling and there is no doubling present. Report this Post to the Staff
Dowhat Pillar of the Community United States 876 Posts	Posted 02/26/2022 2:47 pm So what do you call it? That is my question. I do not need to know what it isn't. There are numerous things it is not, clearly. I would only like to know what it is for future reference. Report this Post to the Staff
ijn1944 Bedrock of the Community United States 19127 Posts	Posted 02/26/2022 3:26 pm Yes, old dies. You are correct. What you're seeing is the result of striking coins using dies with very little life left in them--dies which are deteriorating. Report this Post to the Staff

I simply gave you the meaning of DDD for your own education which apparently you don't need. Correct typo Edited by JimmyD 02/26/2022 4:31 pm Report this Post to the Staff
Dowhat Pillar of the Community United States 876 Posts	Posted 02/26/2022 5:17 pm Thanks all for the replies. Now that the anomaly has been isolated, can one of you explain to me what causes the Sunray appearance of the deterioration from the central point of the strike towards the rims. It is quite semetrical and appears to be raised above the normal fields. Kind of like a strike through but not. Kind of like feeder finger, but not. Many of the outer devices , some would say look doubled. To me they are smeared. Loose dies? I do not know. But someone out there can educate me in this respect, I am certain. It is only for my educational knowledge. It was in the strike. Please explain the mechanics so I can get it. Thanks all. Report this Post to the Staff

Dearborn Moderator United States 95018 Posts	Posted 02/26/2022 10:14 pm Yep, looks like DD top me, The 'rays' you see are flow lines of the metal. Collecting since 1972.

-makecents- Pillar of the Community United States 8733 Posts	Posted 02/26/2022 10:25 pm As others have said, Die Deterioration. It takes a lot of different forms but this was as close as I could find, "Radial Flow Lines". LINK https://www.error-ref.com/radial-flow-lines/ Here are a couple of Lincolns I had pics of that have similar deterioration. -makecents- Edited by -makecents- 02/26/2022 11:05 pm Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 02/27/2022 5:16 pm The term is called die flow lines. It is the direction of the moved metal on the planchet to make the planchet into a coin. Doe this a million times and then you will see die wear at it worst. (despite the mints efforts to make the most out of each die. Despite the three or more times they are polished, these devices get weaker and weaker. Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 03/23/2022 1:38 pm Metal movement over the surface of the die. The dies force the metal into the locations the dies want to move. When this happens hundreds of thousands of times, the lines are what we see on the die from that metal movement. Just part of the aging process. Just like seniors get wrinkles, that is what these flow lines are to a die. Report this Post to the Staff
