<p>[QUOTE=&quot;xlrcable, post: 1726517, member: 41288&quot;]Lately I&#039;ve been opening up some mint sets from 1968-76, and finding the coins even more than usually afflicted by the whitish crud that the pliofilm packaging of that era leaves behind. I&#039;m assuming that others are familiar with this - generally it&#039;s either a haze or a sort of psychedelic pattern of dots and swirls. I&#039;ve seen reports of acetone taking it off, but acetone rarely works for me even after soaking for several days. My experience has been better with distilled water, but only with long soaks that sometimes produce bad side effects. To me, a reliable way to salvage these coins would be a big deal.</p><p><br /></p><p>Yesterday I was looking at some of these and I had a bottle of Verdi-Care nearby, so I thought why not. First I tried the method of soaking one side of the coin for a few minutes, then on some others I simply patted the VC on with a microfiber cloth. In all cases the white crud disappeared completely, and has stayed gone now for 24 hours. These were cents and dimes.</p><p><br /></p><p>Since I&#039;m a bit skeptical by nature I wonder if anyone else has tried this and if the results have held up for a longer period of time? I&#039;d love to think that the Verdi-Care is actually dissolving the bad stuff into oblivion, but there&#039;s no rubbing involved and I wonder if it isn&#039;t just rendering it translucent somehow - not that that wouldn&#039;t be a great improvement anyway.[/QUOTE]</p><p><br /></p>
