Usually unique or at least very good looking, but there are cheap ones of these too. For some people it means expensive. For others it means harder to keep. Usually, they are both expensive and hard to keep since harder to keep corals that are nice are more expensive with limited supply and high demand.
Sometimes, it is just corals that are new to the market. At one point, Walt Disney, RRC Pink Cadillac and Fox Flame were high end, but now they are just average at best. Corals can change from one category to another.
For everybody, it does not mean corals that they see in a lot of tanks that do very well... like huge colonies that you see in a LFS that nobody wants frags of anymore.
