I agree: It appears to be gold plated brass, similar in metal appearance to a gold plated guinea denominated gambling chip.
Thickness of the core is adjusted to match the weight of a Florentine Florin [Florence (Italy), the City where the well respected gold trading coin got it's name from] ~ 3.5 grams.
Looks to be much too circular to be characteristic for a coin struck by the hammer method. Instead, it appears the be blanked out of rolled strip, before being pressed in the same way, as with a modern coin.
