This particular effect is called "trailing" and is a machine error, but cool example. I don't think it adds or takes away value.

Quote:Trailing might look like the letters are doing, but "coin trailing" is not a coin term. This coin is suffering from a late stage Die Deterioration from over use. To be fair, he didn't use the term "coin trailing". However, Trails, Die Trails, Trail Dies, and Die Deterioration Promoted by Trails are all acceptable terms, so Dmil070182 gets the point for that one. On the other hand, I agree that this is strictly due to an aging and overused die as Trail related deterioration generally flows obliquely from the device towards the rim, rather than directly. We'll call it a draw and the OP can keep his Lincoln for educational purposes. |

Quote:Generally speaking, trails are parallel raised ridges which extend away from the corners of a coin's design elements. They are strongest at the point where the device meets the field, and then taper off as they extend into the field. They vary in strength from naked-eye obvious to barely perceptible under magnification. A single coin can exhibit multiple sets of trails going in multiple directions. These ridges are created during polishing of the die by a rotary tool. A soft buff or bristles penetrate into the die's recesses, gather in the corners of those devices, and then erode a gouge into the die as they exit the recesses into the higher relief of the field. Trails can also occur on a coin's incuse devices, which are raised on the die. In this instance, the buff or bristle concentrate against the raised wall and continue gouge out a trail into the field where the device terminates. Since there is no change in relief in this instance, the trails are weaker. "Wavy Steps" are just trails that extend into the steps from the columns on Lincoln cents, causing the steps to have a wavy appearance. For a more detailed explanation, please see the article "Unraveling the Mysteries of Trail Dies" by Will Brooks in the July 17th 2017 issue of CoinWorld Weekly. http://www.traildies.com/ I put the definition because it is confused with Die Deterioration. For the year 2000P they are only 4 variety listed, maybe a good idea it is to be send for evaluation. |

@ Wrekkdd: Not really. mortar sets it is a very old nomination of other kind of die variety. date from 50-60 years ago. Still be keep in the Canadian lexicon due to the fact of reticence to changes by a wrong understood conservatism.

@silviosi, interesting and thanks. I believe there posted a more modern coin that had "mortar set" or something I'd the like, I want to say it was a toonie but I don't remember, I would have to look through my old posts.

COOP explain very well. Me I posted the explanation of traildies cause the term was mention and not to be confuse many of us. The Canadian "Mortar set" in my opinion it is an Die Deterioration which in fact it is a variety. |

As others have indicated, die flow lines like those seen on the OP's cent have nothing to do with trails (trail lines). And trails have nothing to do with Die Deterioration. Trails are die polishing grooves. Error coin writer and researcher.
