Books related to Gold Investment

I went to the Library last week, and find some good books to enhance some additional knowledge in regard to the Gold investment.
The books are ;

1. The Islamic Gold Dinar 
2. The Theft of Nations

Both books written by a scholar, Ahmad Kameel Mydin Meera, which are good for a layman like me to learn and learn. May be I could elaborate further on its contents in a later stage-Insyallah.
