  definitely 1, 2, 3, 5, and 6. nothing minted post 2000 could tone "naturally" in that time. each of them must have received SOME "help"

  Perhaps the 76 Kennedy didn't recieve any help (although it could have used it), the rest are most likely at.
  Besides the weird colors, Darkmane is right.......... there is no way these coins could have naturally toned in a couple of months!

  All but the 76 Kennedy. What's the educational part?

  They are all AT. The educational part is that these are all definately AT so you learn what AT can look like. It seems like more of these coins might have passed for NT if they were older, especially the ones with red in them.
  
  It was educational for me to see that AT Coins could have one sided toning with this much red on them. I was totally surprised by it. A little over a year ago I did some shake-n-bake AT experiments (sulfide chemical in the oven) one night and the coins pictured above coins were the failures. As I remember, these ones just had a hint of color and were basically more brown than colorful. I put the failure coins into a jar and put them in a cabinet above the refrigerator and forgot about them. I stumbled onto the jar today and took them out and looked at them and noticed that the colors seem to have been enhanced on them. Below is a picture of the non-failure colorful ones I made that night, they basically still look like that, only a shade darker. Notice that none of them have the red color that some the failure ones developed, the closest color was reddish-purple. Strange.

  i recently did an experiment using some cardboard sulfur-containing holders. i used cheap coins (unc clad 65 quarters) and started baking at 160 degrees. cooked for 2 hours... no results.... slowly moved up to 290 degrees farenheit. finally i got some perephiral brown to some stunning blue toning. quite nice looking..... unfortunately, the toning was removed by slight contact. this was proven when i showed a roommate (no regard for coins) who thumbed (while i gasped) one of the quarters. looks like AT requires more time and effort than i would have imagined.
  
  
  sorry for the confusion.... i've had a few drinks.... i'll make sure to edit this tomorrow.

  Except for the fact that it is 2004 and impossible to naturally tone that fast.. the color does not scream AT like the rest do.
  
  I would recommend any inexperienced people interested in toned coins to make their own AT coins. They are great to study and see what kind of patterns and colors can be created. Its also lots of fun
