Even if it isn't worth anything, knowing where/when it was made would be great! Thanks! Image can be found at http://pics.livejournal.com/obsessivexidiot/pic/0000sckx/ Which is livejournal, so it's a safe site.
Not positive as the top character can't be read, but I think it's: China, Northern Song Dynasty, Emperor Zhen Zong(998-1022). Xian Ping yuan bao clockwise. Cast from 998-1003.
