Hey eagle! I like collecting red wheaties too! I have sets labled red, green and black. here is a section of the red set that is ever growing! lol
Red Sense!

Rainbow toning and such just makes the coin suspect to me. With some basic metallurgy it is easy tone a coin. I presume everyone here knows this? Ok not easy, I guess its like cooking, just follow the recipe. I have/had a purple '26 that I know was not purple 10 years ago. I don't remember wiping anything (solvent) however I have used denatured alcohol, toluene, acetone etc in the past to clean crap off a coin. I must have done something to it. I posted about it in one of my first threads. Anyways... since it looked like a sore thumb, I decided to fix it. I suspended the penny in sealed jar over a 10% solution of NH3 and water for about 30 minutes and viola! nice and light brown once again.
I should post before and afters.
BTW - That solution is very corrosive. Make sure you don't care about the value if you want to try it. Every coin will react differently depending on the starting point.
I am an extreme newbie to the political intricacies in the delicate subject of creating eye appeal ie. cleaning and toning.. Like the signature I saw on here - you didn't pay for this opinion, so take it for what it is worth - or something like that......
I know, OP. I am sorry. you didnt want to create a debate, but I have to get this off my chest.
IMO: There is no difference in AT vs NT except semantics. The colors you see are oxidation from a reaction of chemicals introduced in proximity of said colored coin. duh... Since some unseen force of nature did not introduce the chemicals, it can safely be said that it was done by the human hand. Whether accidentally or on purpose is inconsequential IMO, it happens. So, therefore if you like colorful toned coins, then study up! You can have every color of the rainbow on every coin for probably the cost of one of those coins.
Blasephemy, I know. Don't yell at me I am new here!
BTW - I checked: I like some toned coins. I like the red, green and black ones, I find in all sorts of weird places.
