[QUOTE="Clawcoins, post: 3494577, member: 77814"]The term "Ridge Rings" is related to Die Deterioration. Not just for US coins, but for any country that mints coins and use their dies a bit too long. article about foreign rings ==> [url]https://www.coinworld.com/news/world-coins/2014/02/source-of-raised-rings-on-world-coins-remains.all.html[/url] And of course, a "ridge" could be part of a design too. The Pence example is 23.66mm diameter. Your 94 quarter looks fully formed to 24.3mm. But let me ask you a question. How can you prove beyond a shadow of a doubt that, say your quarter was minted on top of a foreign planchet, or even a foreign coin? What would have to happen in order for that to occur? Have you considered the mint machine basically compressed a bit too much and made it a tad thinner, which could accelerate die deterioration ? I believe you are actually stating that a foreign coin was minted on a US Press. But If a foreign coin was used that had a Ridge Ring .. wouldn't it be changed by the minting process (and wouldn't you see ghosting) .. the die isn't going to skip over a ridge ring just because.[/QUOTE]
