[QUOTE="Howard Black, post: 3456120, member: 97119"]I'm breaking with my (recent) tradition, and making a rare appearance here (not to be construed as my having ignored anyone; I have indeed read all the comments), because I am 90% certain I've figured out what caused this damage. I do [I]not[/I] believe it was gouging by edge die letters sticking and scraping. I base this on two things: first, the letters are nice and crisp, with no evidence of having dragged, smeared, scraped, stretched, and so forth. Second, I saw [URL='https://www.youtube.com/watch?v=A8bVC52xnFE&feature=youtu.be&t=22']a recently posted video[/URL] (posted by the U.S. Mint), which shows the striking of the new 2019-W quarters. In this video (the link "cues you up" to the point just before the operation in question), it shows the vertical striking of the coins at the West Point Mint. The machinery uses two metal plates, each with a (presumably hemispherical) slot. They move together to grab a planchet, then slide it over the anvil die, and then open, releasing the planchet. The hammer die then strikes the coin, and another (apparently identical) set of plates move toward each other, grabbing the coin, which is them carried sideways and dropped down the chute. The video is best viewed full-screen, at 0.25 normal speed. I believe that this coin was processed in a similar machine, in which [I]quarter[/I] sized plates were accidentally installed (or not "de-installed" after having done a run of quarters), thus causing the four equidistant gouges -- gouges which [I]underlie[/I] perfectly struck lettering. If, as I suspect, this is what has occurred, then there were almost certainly more than one such coin produced, [I]most[/I] of which were intercepted and directed to the crunch-o-matic coin-wrinkler. I say that I am [B]90[/B]% certain (rather than the usual "99%" used by folks who are "nearly" certain), because I do not know if this was indeed the process used for the production of this coin. But, logically (I used to make a living producing [I]working [/I]logic), it fits all the known evidence. N.B.: "Known evidence" means evidence known by [I][B]me[/B][/I]; and I can with a clear conscience attest to the fact that I am the [I]only[/I] one who has [I]seen[/I] the full evidence, as I can also attest that the photography does [B]not[/B] show the full evidence. That said, I make no bones about the reality of this being conjecture. But, as conjecture goes, I think it's pretty good conjecture. I will probably call a TPG or two, and ask them if they're familiar with this, and, if it's something they'd grade, or just take my money and tell me to have a nice day. (IMO it will be easier to convey an accurate description verbally/interactively than via either my shoddy images or my shamefacedly prolix endeavors.) Just kidding. (Or am I?) [[That's the best I can do in emulating Kirk telling the ship's computer to calculate Pi (or however it was that he put it when I viewed that episode in 1960-something).]] <g,d&r>[/QUOTE]
