The story of the amulet

Just read the story of the amulet by E. Nesbit. The take takes place in 1905 and I presume was written at around that time.  It is in a similar vein to the lion the witch and the wardrobe but without the religious undertones. Although it is a child's book I certainly enjoyed it. I read another book about an amulet as a child in the early 70s but can't remember which one, does anybody have any ideas about what it might have been?
