<p>[QUOTE="mlov43, post: 2059629, member: 16729"]There has got to be a text resource on these silver One Yen pieces. Filing the rims sounds like PMD, just because that seems like something a "bullion thief" would do, to hide the fact that silver is missing. If the mint did it, I would think that it would appear as "filing marks" that would go all across the face of the coin, or planchet before striking, or in areas of the fields. Kind of like other countries' silver coins of earlier times. These coins were made starting in the Meiji era (1870), right? I don't think that mint filing (to reduce the weight of a slightly overweight planchet) was done at this time in major mints. I gotta fact-check that, btw... Anyway, I would imagine that size/weight ratio tolerances were tight enough by then to elide any filing by the mint, since filing and weighing was done by hand(!)</p><p><br /></p><p>I've seen many of these One Yen silver pieces, they are very attractive, and I've never noticed rim or filing damage of any kind on XF to MS coins, unless it was dings, graffiti or chopmarks, of course.[/QUOTE]</p><p><br /></p>
