One-piece Zodiac Sculpture

A sculpture is spherical as a whole, all of which are horses, cows, sheep, pigs, dogs, chickens, dragons, snakes, rats, monkeys, tigers and rabbits, standing on the Gu Song, or stepping on ancient coins and ingots. There is an ancient coin under the front Tiger Claw, which reads "lucky money, treasure" in traditional Chinese characters; The base is a disk with a height of 1 cm, and the periphery is engraved with lace. The base is engraved with "What is capable and what is long?" The pattern carved on the top ball is also the zodiac. The material looks like jade, but I don't know what it is. Please identify the material and value of this article.
