Definately ivory. The crosshatch pattern on the bottom are called Scrager(?) lines and are the definitive mark of elephant/mammoth ivory. If you search "identifying ivory" you will find a site called "is it real or is it fake". Check it out and it will give you all you would like to know about spotting ivory. This information is a must for any garage/estate sale junkie. I find one or two pieces a month, almost always the people who are selling it have no idea what they are selling. The pin test is unreliable and could damage a valuable piece. Nice Indian goddess, I'm jealous. From the browning on the back, I would say pre-war for certain, possibly 100 years. The golden color on the back comes from skin oils after handling it. Probably go for $80-$100 on Ebay, but now is not the time to be selling ivory. In a number of years, I expect the price to skyrocket once easily obtainable mammoth ivory becomes more scarce. Did I mention I'm jealous.
