The Holy Grail  among Potter stuff\n\n Earliest editions of Harry Potter and the Philosopher's Stone are precious because only 500 copies were ever printed and 300 of those were donated to libraries. If you own a copy with the author's name printed as Joanne Rowling  then you might be sitting on a small fortune.

Prisoner of Azkaban is especially rare and is usually priced betweenR$1,500 andR$2,000. There were only 7,000 copies printed. There were 12,000 copies of the 1/1 Philosopher's Stone and 17,000 of the 1/1 Chamber of Secrets printed.
