That is hysterical. Not even sure it is NT, although NGC disagrees with me. Crazy markup. Toned coins that are attractive do demand big premiums, but I don’t even think a sucker buyer would go for that much markup.
Quite ridiculous but some people make their living buying off ebay and re-selling on ebay for a higher price! It's not just with coins either as I've seen it happen with signs too! They must live like hermits!
Fine examples of why I stay completely away from rainbow toned coins. It's enough that I'll be unlikely to see a profit on even part of my collection. And that's buying at reasonable prices. I can't justify paying extra for pretty colors even if they are NT.
To each his own; your coins are amazing in my opinion. I do like stuff with pretty colors though and don’t mind paying up for it. Here’s my example of this date- the reverse is not as attractive as the obverse but helps tell the story of how this coin toned, still cartwheels nicely and indicates its originality despite the unusually vibrant colors.
