Souvenir token. May not even be gold
I believe the red book says that any "California gold" coin with a bear on it is a modern replica.
It is a genuine fantasy. No coin produced in the 1800s ever looked like that.
Really looks off to me.
I remember some of these tokens in 1/4 and 1/2 dated 1852 thru 1856, but do not know whether gold or not. Here is a website describing their creators and why.
That is a souvenir token and not a U.S. coin... Likely not gold. Cheers, RickO
Woolworth’s used to sell them for $2 in the 1960s. “When you see a bear, beware.”
