best book on the gold standard

looking for a title about the history and rationale of the gold standard. no conspiracy or kooky stuff. something pragmatic. thanks in advance and sorry if this was the wrong forum for such a specific request.

The Power of Gold: The History of an Obsession is a good’un. The best general history I know. No conspiracy stuff. Starts in ancient history and develops into the 20th century. A honest exploration into why gold was chosen in the past but would no longer work so well today.
