<p>[QUOTE=&quot;GDJMSP, post: 1371150, member: 112&quot;]People call a whole lot of things milk spots, which is the point of what I have been saying in this thread and the other. If you sneeze, cough, or even exhale hard over a coin, small droplets of moisture often get on the coin. These droplets will be whitish in color once they dry. (but they will change color later) People call those milk spots, but they are not. So what do you call them ? I dunno, call them what they are I guess - spit ? Snot ? But they are not milk spots.</p><p><br /></p><p>Same thing with the coins in the video. Nearly half the coin is covered - that&#039;s a spot ? Yeah, I know, picky maybe, but gimme a break. When half the coin is covered by something that is not a spot ! The only reason people call THAT a milk spot is because of the color. </p><p><br /></p><p>So what is it ? It&#039;s contamination obviously. And yes it probably got on the planchet prior to minting. And it is, in my opinion, most likely a residue of some sort from the washing process. So if you want to call it something, call it dried soap residue. </p><p><br /></p><p>The thing that differentiates it from milk spots is this - we don&#039;t know what milk spots are or what causes them. Milk spots cannot be removed. Dip a coin with milk spots in Tarn-X, one of the harshest and strongest dips there is, and the milk spots are still there. Dip one of those coins shown in that video and the whitish film disappears and is gone forever.</p><p><br /></p><p>Milk spots sometimes appear later, even after a coin is slabbed. But they are also often found on coins freshly obtained directly from the mint. Of course those coins may have been sitting at the mint for a month or so before they were shipped out - we don&#039;t know. We only know that sometimes they are there when we first see the coins and sometimes they show up later. But they are always small, often irregular in shape, spots. And they appear to be <u>in</u> the metal itself, not <u>on</u> the metal. Which is why we can&#039;t find anything to remove them. </p><p><br /></p><p>With the coins in that video - the stuff is <u>on</u> the metal. Which is why it can be removed. Same thing for spit drops, they can be removed too.[/QUOTE]</p><p><br /></p>
