Santa Clause 11” Glass Statue Figurine Vintage Christmas Holiday Decor 14” Round

Excellent and Clean Preowned I asked a group of experts what type of glass this is but they all had a difficult time so we do not know for sure. I am fascinated by this piece and believe it is extremely rare- thought by some to be mercury glass or moser but the moser pieces I have found do not appear to be the same type of glass. Any help on this is appreciated-
