An authentic $1 gold fractional produced in 1849 weighs 1.67 gram and has a diameter of 13mm. Your “token” is about the same size but is 1.10 gram too light. I believe it is a plated aluminum replica or a facsimile of some sort. Not a real gold coin…imo…Spark
Is this the coin it's trying to emulate? Not finding any close matches in real California fractional gold. https://www.ngccoin.com/certlookup/6530835-015/65/
Can you post an image of the real thing? I wasn't able to find any fractional gold that matches this.
