It's a good question and one that many don't consider. But yes. Even though the coin may be in a quality holder, it, along with all of your other coins in holders, must then be stored in some larger container that greatly reduces the flow of air around the holders. This is necessary because you then have a smaller climate in which you can control, to a degree anyway, temperature (by storing that container in a cool, drak place where the temp seldom varies) and humidity with the use of desicants.
.....i think SOMEBODY would buy them. just like CAC coins. not EVERYONE goes for the 'umpire' extra opinion on the slabs but people that desire the option goes for it. it may be the only option for keeping the environment out of the color turning equation that causes so much uneasiness with the red/brown subject. jmo
You still think somebody would buy them if they each cost 10 times what using CAC costs ? What if it were a hundred times that ? That's the price range they would be in.
.....i still think there would be buyers. not everyone, of course, but SOME. just like everyone wouldn't buy a rolls royce. some people just have to have it if it's made available to them. if they can afford the product they buy the product.
Thanks - Would a safety deposit box be a good idea then to store them in? I have also heard about the albums for coins but then you wouldn't be able to keep them in a small box right? I appreciate the answers being a newbie!
Personally I would not, but that's because I have built enough banks to know that they tend to keep them pretty humid and humidity is the enemy of your coins. But it can be done as long you go to extra effort to check on them once a month or so and keep fresh dessicant packs in the safe deposit box.
Here is some food for thought: The janitor at the bank may be using Ammonia based floor cleaners and may be squirting Oxidizing Bleach directly onto your box when they wipe them down once a month/week/day. Then they can close the vault door & trap all those lovely fumes in there.
Say i bought a slabbed proof coin with no toning at the time but after some years of letting it sit it does start to tone and the tone is very nice, would sending it back to the TPG yeld an upgrade or an add on to the fact that its now toned?
It might or it might not. It would depend on if the grading standards had loosened or if the eye appeal of the coin had changed enough that the TPG thought it warranted an upgrade.
Usually it is done by the submittor. Why ? Because they want to remove the toning on the coin. But there have been cases where PCGS has dipped coins without even asking the owner's permission.
While grading is still subjective, the numeric grade assigned a coin is supposed to represent the technical merits of the coin. NGC uses a "star" for certain coins that have eye appeal that cannot be summed up in the numeric grade. I don't think PCGS has a counterpart for the NGC *. It is not likely that nice toning would add to the numeric grade, but it could receive a star for it. Chris
You are right to a point, but exhibit a complete lack in understanding of creativity and function. There are many options available beyond what you think. I'd also like for you to show us a demonstration of how 'easily' a 600+ lb safe is moved up stairs. As for the OP, I store slabs in IS slab holders and boxes. Stored in a cool, dark, 30% humidity, year round location. Slabs are not air tight but provide a great deal of protection. A reasonable amount of environmentally controlled storage and appropriate storage materials should keep them from toning.
I have to disagree with that. The two most important criteria used when a TPG grades a coin are luster and eye appeal - both of which are subjective. And there are plenty of coins that have been bumped a grade or two specifically because they had nice toning. Again, that is because eye appeal is one of the most important aspects when determining the grade of a coin.
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't that impossible to apply.
