Toned Korean hwan.

Blackhawk

This 1961 hwan from South Korea has some neat toning...I don't know if it's AT or not, but it's colorful.

I had one with sort of similar toning, once. Not quite so wild or iridescent as that, but colorful.

Get it slabbed and consign it to MrD ("greattoning"), and make moon money!

(Seriously, though, you Darksiders might wanna consider that with some of your "monster toned" coins- I don't know how the guy does it, but I have seen him sell stuff like common George VI 1/2d with wild toning for insane money, like 100x Krause!)

Very nice, Blackhawk.
