Beware of rainbow toning

Agreed on both points. I personally do not even find this particular AT specimen more attractive than the original, and I like toned coins. It is actually a good case study for toned collecting newbies.

Who says you can't have your cake and eat it too? Rainbow mint set toners...

1958-D PCGS MS66 FBL



Also PCGS MS66 FBL, same date/MM

 

Do you have a link for these toned auctions? Id be interested in bidding.

 

Stop doing that. Doug knows all but the way it works is that we have to trust him and believe. Providing links is not his strong suit.

 

Copy and paste is a very simple operation.

 

You collectors that love Ebay and toned coins should be happy.

Right now Ebay has 17,167 toned coins listed. Of those numbers, 3,591 are PCGS and 3,151 are NGC.

btw, the last 3 ANA shows I went to had thousands of toned coins (New Orleans, Atlanta and Orlando). Doug is correct.

 

so your saying there is 7000 attractive rainbow toned coins on ebay. I doubt you counted. Every coin i list on ebay that has even the slighest toning i list as toned. So i dont think thats an accurate statement. Considering all coins tone over time having a few thousand toned coins at a show when billions of coins have been minted i dont consider significant.

 

Where did I say this?

 

Again, what statement are you talking about?

 

Whats your point then?

 

Do you understand what you read?

 

I did develop my own coin cleaner for high end copper based on chemicals in the lab and based on what worked with the original Coin Care which is now ban because of the Freon TF it contained and its implications to ozone. My product has no metal effects to copper but (YES) when you take 200 years of soil from a surface AWAY there is a visual change. Normally if the coin has not green (Cu2O) issues I leave it alone. Most people like leading EAC people I talked to use the old standby - Xylol. An inert solvent is fine but I find a cleaner if properly done with trace synthetic detergents and the proper fluorocarbon mix works very well.
Recently on a Mexican coin of some value it was purchased cheap but had SEVERE black oxide coatings on both the obverse and reverse. Interestingly after SEM/EDS it indicated this was due to due to probably salt water corrosion. The Red Rose CC patron here (BTW - how is Byron Weston doing - BTW?) mentioned thiourea. I did not use the citric acid (mild organic acid) additive but it worked. It did create a grayish overtone but most if not all of the black gook was removed which I thought was inert and non-removable. I made $300 on the piece after this cleaning. To me this was not robbery but just improving the surface of a coin.
When I have to tone a coin after cleaning it my cleaner (fluorocarbon-based ingredients - proprietary) I sometimes will wrap the coin in aluminum foil and put it into a an electric oven at 400*F checking it at 15 minute cycles and expediting the 5% Cu do its work naturally on the toning of the silver alloy coin. To me for sure is AT but I do this on coins that normally have corrosive or oxidative residues which should be removed. Only on silver issues.
The danger I have in cleaning is hairline scratches so I am normally very careful with UNC specimens and in most cases will not touch these coins at this level if RAW - of course.

Sometimes. are trying to insult me or is that an honest questions?

 

Not for nothing, and not that I am saying I agree or disagree, but just for the sake of credibility; that is a pretty flimsy group of statements.

You state the links exist, but that you can't, or won't, post them - hmmmm ok.

Then you say that "if " one knows the coin market, then they HAVE to agree with you and your assumed "common knowledge". In a court, that wouldn't hold up brother.

I guess on this forum as judge, jury and executioner, you can get away with saying whatever you want, but don't be surprised when your perceived credibility begins splintering and crumbling. And if we are being honest, as of lately, it seems to be. Again, no need to flex the mod muscle, sometimes we just don't know, or care even, how we are perceived. In your case I think it is because of your position and the fact that you would are the "emperor with no clothes on," with all of the forumites afraid to tell you. Remember, it is only after we recognize our own faults that we are able to grow.

 

So break it down. There are 150,000 pcgs and ngc coins on eBay today. As you said many coins are simply listed as toned. A quick look shows only 1/10 worth a premium, but lest be generous and call it 1/5. The math shows less then 1% of the coins listed on eBay as attractively toned. The math speaks for itself.

 

yes, and all GDJMSP's auctions of the past where every coin was toned have discontinued. The coin doctors must have made so much money and retired.

 

I just got back from a show today, I looked through maybe 50 double row red boxes full of coins probably 200 coins a box and came home with 7 toned coins, nothing great, but bought every toned coin they had. I guess all the toned coins were plucked before I got there and are heading to GDJMSP mythical "Toned Auction".
