That was the notation used on both JP wikis. The kanji used are 序 中 上 特 極, which are "Low, Medium, High, Special, and Highest." I'm not sure if those are official labels, or if both wikis decided to use the same labels.

I've been wondering whether we should change our labeling system to make more sense in English (ex. Low, Medium, High, High Rare, Highest), but I'm really not sure.
