JR, I think you're wrong. There's enough shine for $25 each.
JohnF: The genetics of carp are terribly complex, but like purebred dogs or cats or horses, there are certain traits that should be present to be considered a particular breed. These are usually not too difficult to identify, but it gets very confusing among the metallics because breeders trying to create new varieties so often assign names before there is much stability. Metallics also present a challenge because the mass market outlets want shiny, sparkling koi... metallics and ginrin sell. But, they also want a wide variety. A tank of soft yellow Yamabuki will not produce the return of a tank filled with a mix of colors, splotches and sparkling shine. The typical consumer just wants a lot of color and splash at the time of purchase. So, breeders fill the consumers' desires by crossing all sorts of metallics together, creating a real hodge podge ....which will sell quickly at 7" for $14.95 at the local pet shop. Then the fellow who bought a pair is given a booklet on koi, he learns there are different recognized varieties and he wants to know which he has. The pet shop clerk will give a name or two, and everyone goes home happy... and misinformed. But, it's OK, because the guy knows that when the fish grow up they'll be worth thousands of dollars.
