Now that is sort of repititious. I would just have said kanga is right-kanga is right-kanga is right-kanga is right-kanga is right-kanga is right. Note the period at the end, not a ,?
Not necessarily. Water is much more dense that air or other gases. Also, there would have to be more than one source of an opening to allow air to escape for the water to enter. Just to play safe and if not ever planning on opening the slab I would consider placing a bead of plastic glue around the entire sides, then submersing in a bath of liquid plastic, then encasing in a metal box where you could pump all the air out, then placing in a concrete slab. Still you never know. Or opening the slab and placing the coin in an album.
Yeah. I remember seeing one of the bigger guys over at the PCGS forum who was toning coins in their slabs.
You assume correctly. They aren't even close. Carl is correct, to make something water tight is much easier than making it airtight. And any slab out there, if submersed in a bowl of water, will fill up with water. Same is true of any other coin holder on the market.
Lehigh, this is what natural toning looks like on a 90% silver dime. That thing, think about it. I know the TPG slabbed it. All that means is they think some poor fool should buy it. But where the heck did this coin have a chance to tone like that, if it was issued in a special set, and never saw the light of circulation? This is costume jewelry, all wrapped up real nice in a slab. JMHO...
I wouldn't presume to tell Lehigh what is natural toning and what isn't, as he's quite an expert on the matter. The slabs were not air tight at one point, and I would venture are not air tight at this point. The book "Coin Chemistry" by Weimar White, speak to this issue when he talks about artificially toning coins that are already slabbed. If one subjects a slab to a concentrated sulfur vapor, the gas can seep inside and tone an already slabbed coin. That being said, the experiments were conducted some time ago, and better sealing methods may have been developed by now. At the MSNS show this past fall, I saw a dealer with ridiculously artifically-toned coins, all modern (like 2004 silver eagles, for instance), all in PCGS slabs. My best guess is that, unless he knows somebody at PCGS, these slabs were gassed.
No, that is just what 1 example of natural toning looks like - there are thousands. This coin has natural toning Eddie, it's not uncommon and no it doesn't take decades to occur either. Under the right conditions natural toning can occur very quickly. Take this coin for example - it took about a year. It used to be in my collection and is now in my son's collection. And it is 100% natural.
You showed this before in other contexts and it's breathtaking. But you know what we all want to know, now, don't you (you having had exclusive custody of this coin)? Under what conditions did this happen in about a year's time? Spill the beans.
I agree with Categories 2 & 3. Regarding category 1, what will happen first? The collapse of the toned coin market or the people that predict the collapse admit they are wrong. I don't mean any offense, but people have been predicting the collapse of the toned coin market for about 10 years now. Every year they make the same prediction and it simply doesn't happen. I have tried numerous times to explain why it will not happen yet my logic and reasons seem to go unnoticed. Collectors have always paid a premium for toning and this will continue. The size of the premium is related to the quality of the toning and it's effect on eye appeal as well as the price of the same issue devoid of toning. The lower the price, the higher the premium. And this may be semantics but you said there will be a lot of disappointed collectors. In my eyes, collectors rarely consider the resale value of the coins they purchase. They may consider it if they are over invested in coins, but for the most part, that is an area that affects mainly investors in rare coins. As a collector, I would love the toned coin market to collapse. Then I could buy all of them for cheap. I have no intention of selling my collection unless an unforeseen financial situation forces me to sell.
airtight equipment exist like for space travel i wonder when they will make something for the coin market
You know what, tulips did pretty well in the early 1600's. I heard one was once traded for 12 acres of land. However, by the 1637 the market collapsed and they once again were just flowers. Sports cards did quite well for a long time. So did stamps. I even know a person who made a killing from beanie babies. Do you see a trend? Don't kid yourself that toned coins (or any collectible) will be any different in the long run. Historically yours...Mike
By that methodology, you can't single out specific coins. The whole coin market should/will collapse. I know one thing, the coin in this thread aint never gonna sell for $10. I believe that it will one day sell for $75, because that is a realistic adjustment to the lunacy exhibited in the bidding for this coin. But for this coin or toned coins in general to sell for no premium is extremely unlikely. Logically yours..Paul PS. You know way to much about flowers from the 1600's. Might come in handy if you are ever on Jeopardy though!
Agreed on the collapse thing -- that was kind of the point. And I'll tell you two ways to make that $75 coin into a $10 one. First, crack it out of the $65 plastic and try and sell it. Second, the one who ATed it publishes the recipe on YouTube. Unfortunately (or fortunately, depending on your perspective), neither of those is likely to happen. Have fun...Mike
the whole coin and currency market will collapse and they wont be worth a lot of money. but when is the key question? i dont think it will happen during our life time ( i dont mean prices wont go down or up but the hobby wont be wiped out)
I agree with that, without that PCGS plastic, nobody would touch that with a ten foot pole. But once they say the toning is market acceptable, let the bidding wars begin.
Yeah, my first bid was $75. I was outbid on that last day and before I knew it, the coin was at $155 (the winners original bid). I decided that it might be many years before I come across another 90's silver proof dime with rainbow toning in a slab. This made the coin more valuable to me since I am creating a registry set of rainbow toned 20th Century coins. The damn registry people added these stupid 90's proofs to the set. For what reason, I don't know. But anyway, I decided to make a completely ridiculous bid of $310 with 1 hour left in the auction, thinking that nobody could be crazy enough to outbid be. Well, I got outbid by 2 people. I didn't know they allowed mail in the looney bin. You know what I hope. I hope that coin sucks in hand and the sellers photos are juiced more than usual. Serves that dude right for bidding $380 on that coin.
