Coinhole Valued Member United States 99 Posts	Posted 03/25/2022 3:05 pm Hi. I found this nickel coin roll hunting and obviously it stuck out like a sore thumb. I've never seen one as bad as this. Could this be alot of grease or a real worn die? Thanks I just like to know what I'm looking at. I actually enjoy the real science behind coins like this. The ripple effect just seems physically impossible. Report this Post to the Staff

nick10 Pillar of the Community United States 3207 Posts	Posted 03/25/2022 3:38 pm the "orange peel" look is from a very late die state, that's a fairly nice example, might be worth keeping just for that, but realize overworked dies were common during that era Report this Post to the Staff
Coinhole Valued Member United States 99 Posts	Posted 03/25/2022 4:05 pm Thanks. I appreciate it. So the die gets so worn down that it develops pathways for the metal to flow under the extreme pressure of the strike? Interesting. I have seen many minor examples on dimes from the 1980s. Never a nickel this orange peeled. Report this Post to the Staff
nick10 Pillar of the Community United States 3207 Posts	Posted 03/25/2022 4:19 pm during use, the die gets worn by the planchets, preferentially in certain areas, and with time that wear amplifies into the orange peel look on the die as well as any coins it makes Edited by nick10 03/25/2022 4:20 pm Report this Post to the Staff

Essentially, yes. It's not physical wear on the face of the die, but rather when the die strikes the planchet the energy from the strike is transferred laterally across the face of the die towards the rim. Over time, this causes the metal in the die to deform. In harder metals, like nickel, the result is more often what are known as flow lines forming on the die. Notice how the lines radiate out from the center of the coin? On softer coins, like cents, you'll actually see the designs themselves get pushed out towards the rim. This is called Die Deterioration Doubling and looks like a second or "shadow" device appearing on the coin. You've got a really cool example of really bad quality control at the mint. Frankly, the 1980's were not a era the mint should be proud of. Cents, nickels, dimes and quarters are all notorious for examples of badly overused dies. Report this Post to the Staff

Coinhole Valued Member United States 99 Posts	Posted 03/25/2022 6:31 pm It's weighs a hefty 5.07g just a tick over what I imagined. Would those extra ripples be the cause? Report this Post to the Staff

Coinhole Valued Member United States 99 Posts	Posted 03/25/2022 7:09 pm Ha. Sounds pretty dumb know that I think about it. Still the same amount of material. Report this Post to the Staff
Coinhole Valued Member United States 99 Posts	Posted 03/25/2022 7:21 pm I don't think it's plated. I just used a bunch of natural light to get the ripples to pop out. This is different lighting. Report this Post to the Staff
