Apparently the rainbow toned coin market is doing just fine. I just bid over 30X wholesale on a 1995-S Silver Roosevelt Dime PCGS PR67 and lost the auction. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=260360658801 And I thought I was going to be able to pick this one up for my original bid of $75. There are way too many crazy people out there.
It's high, but not outrageous. Common mint set toned wheats in 64-65 RB go for double that at times, I have seen triple. A complete set like that would be breathtaking.
I wish the geniuses at NGC had not added the 90's silver proofs (dime-quarter-half) to the 20th century registry set (proofs included). Try finding slabbed rainbow toned proofs from the 90's, it's not easy. Honestly, I didn't want to bid as high as I did. This seller juices his photos a little and toned proofs look very good in photos, but not always as impressive in hand. If it was a 69DCAM, I would have bid higher.
My opinion is that there is no chance that coin "naturally" toned in the last 13 years. Either the coin is not as vividly-colored as the pictures would indicate, or it was intentionally exposed to contaminants. The brownish color of the reverse screams highly-concentrated sulfur to me.
Yes, this is probably not natural toning at all! This coin has been doctored or hastened - if you doubt what I say let me tell you that I have myself toned coins like this artificially when trying to experiment with different things. By the way, at anytime that I sold or traded these type coins I have disclosed that they are artificially toned coins each time. It is not easy to get one like this but if you keep trying you can do it. Regarding this dime though ask yourself, How many other coins of this era have you seen that even come close to this one that are thought to be natural? It is possible (barely) that a toning expert put several of these in the right atmosphere and got one to come out like this on purpose. It can be done in a humid summer attic inside sulfur containing envelopes. Not likely but possible. There is a couple of little known ways to easily determine artificial color or coins that have had a procedure done that hastens the toning process but not on slabbed coins. Here's one of them - if you have several coins that are suspect put them out flat so you can almost look across them, like if they are in a page and you can see directly across the flattened surfaces and turn the coin or page as you look - at one point the artificial color on the coins surface will all diminish from colors to mottled grey or dark surfaces. You can not quite do it in a slab though - a true toned coin will also diminish but not as dramatically as the artificially toned coin. A few years ago there was a group of Lincoln's on eBay described as gem early forties that were put in tissue for over 40 years from Florida. I think there were 70 pc. and he wanted $70 or so and I took a chance got them and there were the most beautiful Lincoln Cents you ever saw - not only were they rainbow toned in every color they were early die state, (as if the man knew exactly what he was doing) I sold (or gave to close friends) all but 2 of them, the very best ones. I think I made about $550 of the remaining nicest ones but they indeed were spectacular. I have nickels and some dimes and a few half's like that also. But in the end what's the difference between artificial toned coins or coins that have been advanced or hastened to tone. I say if you like them buy them, if you don't stay away. One more thing to remember whether artificial or not the coin, at it's most spectacular will probably degrade from there. In other words it's colors will never be better and as time goes on it will eventually not be as good - we can't deny that, that is the nature of the beast.
My Prediction: Sometime in the not too distant future there will be a LOT of disappointed collectors. Category 1: People who pay an excessive price for NT coins. If you like them, fine. But keep the cost within sane values. (The AT buyer will probably be disappointed sooner.) Category 2: People who pay an excessive price for modern coins graded MS-70 or PF-70 by the major TPGs. I see a LOT more of those coins making it into those holders thus depressing their value. (The buyer of SSS coins will probably be disappointed sooner.) Category 3: People who pay an excessive price for modern error coins that are proving more common than expected. A prime example is the early Presidential dollars with no edge lettering. I believe some of them went for over $1000. These people are already among the disappointed. Sub Category 3.1: People who pay an excessive price for modern error coins that aren't errors. A prime example is the early Presidential dollars with edge lettering "upside down". They aren't errors. They are just examples of the random nature in the way the lettering was applied. These people are also already among the disappointed. Any others?
kanga is right kanga is right-kanga is right-kanga is right-kanga is right-kanga is right-kanga is right, Very few truer words have been spoken since I've been on this site! Well said!
That is a question that I have been meaning to ask. As time goes marching on the spectacular toning that many of these coins exhibit is going to diminish?
The colors will only change if exposed to air. If you could keep them in an airtight container, they would theoretically stay the same for a very long time. Further exposure to air/contaminants will cause the existing colors to darken (they move along the progression of the rainbow), until eventually the entire coin would be covered with the thickest layer of silver oxide, and be black.
Are TPG holders airtight? Are TPG holders airtight? As you know I hate them so I don't know much except none of the earlier big three were airtight - has that changed and when?? If you are assuming sealed coins in hard plastic holders are automatically airtight think again. Don't you have to pull a negative air pressure on them as they seal to really do that? And isn't that kind of a laboratory type procedure that should be rather expensive? Even more so than these crooks, I mean guys charge??
Actually, no and no. Ever buy a package (brick) of coffee. Maybe it is not cheap (the coffee anyway), but not done in a laboratory and not that expensive. BTW, if it were not air tight, it would no longer be a brick. Your first question was are the holders air tight. I have heard nothing about a guarantee to that effect, but I will bet that 99% of them are about as close as you can get. Now Doug is going to come by and tell you that the plastic is not a perfect seal. Technically, he is correct, but I will bet if you put the coin in a vacuum originally, it would be centuries before the vacuum would be lost. That is not perfect, but darned close.
Toss a slab in water and hold it down. That will tell us if they are airtight. I assume they are not.
