If that's real ivory or tusk of any kind...bad juju. Wouldn't want that anywhere around me.
Why hippo ivory is legal in every state as is mammoth ivory. I have bought lot of hippo and Mammoth ivory. I still get sent offers for lots of mammoth. Old walrus ivory is also legal.
There are some pretty sever restrictions on elephant ivory, but owning that piece would be 100% legal due to its age. Selling those across state lines would be legal if they weigh less than 7 ounces and I am sure that ivory was imported prior to January 18, 1990 were crafted prior to 2016

What Can I Do With My Ivory?
The de minimis exemption applies only to items made from African elephant ivory. The African elephant 4(d) rule provides an exemption from prohibitions on selling or offering for sale in interstate and foreign commerce for certain manufactured or handcrafted items that contain a small (de minimis) amount of African elephant ivory. To view examples of items that may meet de minimis criteria, click here.

(ii) If the item is located outside the United States, the ivory was removed from the wild prior to February 26, 1976;
(iii) The ivory is a fixed or integral component or components of a larger manufactured or handcrafted item and is not in its current form the primary source of the value of the item, that is, the ivory does not account for more than 50 % of the value of the item;
(iv) The ivory is not raw;
(v) The manufactured or handcrafted item is not made wholly or primarily of ivory, that is, the ivory component or components do not account for more than 50 % of the item by volume;
