This link, and I bet any other one you found, are irrelevant in terms of premium toned coins. I can't speak for other toned collectors, but "gold" toned coins are certainly not a "toner" in my book. They would bring absolutely no premium whatsoever. Sure there are plenty of ways to "tone" coins, but they will all look like you toned them. I think you are missing the point about what is considered a sought after toner. Think of it this way: Art forgeries are certainly a problem and some are very good copies. If you can't tell the difference between the forgery and an original, then you shouldn't be buying art. Show me one artificially toned coin that looks like these, then we can discuss more.
I would say that these are well within the "market acceptability" range, and TPGs agree with that--just like Greg's coins. Now it is a matter of taste,but most coin buyers would like coins like this???
Same goes for these--I've not in any way questioned authenticity, and to me, they are a canvas painted in beauty. I guess it is in the eyes of the beholder.
Take the minute or so and find out that you are mistaken. The "Peacegate" incident did not cause a collapse of the rainbow toned coin market. I have been buying and selling rainbow toned coins for over a decade. It is not a fad, and the premiums are not simply going to disappear. In fact, the only drop in prices over the last decade came in 2009-10 as a result of the recession. Prices have rebounded a little but are not at their highs which were reached in 2007-08. Ironically, the hottest area of toned coinage these days is toned Peace Dollars, including a $10K+ 1923-S that just sold a few weeks ago.
HEY PAUL, good to see you. Agree totally with Paul--there was an artificial high in the market for toned coins in the last 2000s, and prices were totally out of hand. However, I, too, have been buying and selling toners over the years, and find that the market is, was, and will most likely always be strong, as many folks who are collectors are attracted to the esthetics of toned coins, and don't in any way see them as "lesser" coins for their color, but have a perception of them as works of art.
