<p>[QUOTE=&quot;CaptainMorgan64, post: 2261589, member: 76144&quot;]Moisture in the Slab??? I just bought a MS69 2001 D Buffalo slabbed by NGC from Tampa, Florida....I live in Illinois and it is fall (Oct. 28). The case looks like there is moisture inside, as where the white coin holder part touches the clear outer shell has a few darker areas (that move...disappear and reappear, like oil/water are there. If I press the case the spot grows and if I squeeze the sides the spot disappears. It is possible the coin became cold on its journey and created this condensation that now may not escape? Maybe not a good idea to buy coins from humid to cooler environments, at this time of the year? I sealed the coin/NGC case in a sandwich bag with a big bag of dessicant/silica gel, hope it dries it out. Is it possible these coins are being sealed in a bad humidity adverse environment? They could seal these in an incubator with inert gas, like they do lithium ion batteries....yeah I used to work there and the process isn&#039;t that impossible to apply.[/QUOTE]</p><p><br /></p>
