Gold is metal that is a homogenous mixture. It is not a heterogeneous mixture, because a heterogeneous mixture can be physically separated.
A jar of coins can not be necessarily called as any sort of mixture as it would include articles of same type. It would rather be better to ask what type of mixture makes up a coin itself. Well, most coins are made up of 'alloy', which is a homogeneous mixture of several metals, prepared by mixing them in the molten state.

this is called a solution. If the solution is holding as much solute as physically possible, it is called a saturated solution.
Mixture
A mixture consists of substances that are physically blended together but not chemically bonded. The components of a mixture can be separated by physical means such as filtration, distillation, or evaporation without changing their chemical composition. Examples of mixtures include saltwater and air.
Mechanical mixture is a type of mixture where substances are physically combined without any chemical bonding. The properties of a mechanical mixture are a combination of the properties of the individual substances present in the mixture. These properties can include color, texture, density, and solubility, among others.
A mixture contains 2 or more chemicals that are not chemically combined, meaning they can be physically separated. Examples include saltwater and air.

heterogeneous
In a mixture, the substances are physically combined, meaning their identities and properties remain unchanged. Each component retains its individual chemical properties and can be separated by physical means.
To calculate the density of a gaseous mixture, you need to know the individual densities of the gases in the mixture and their respective proportions. The formula for calculating the density of a gaseous mixture is: Density of mixture (Density of gas 1 x Fraction of gas 1) (Density of gas 2 x Fraction of gas 2) ... (Density of gas n x Fraction of gas n) Where the fractions of each gas are expressed as a decimal.
If two liquids have the same density, they will not separate when mixed together. This means they are immiscible and will form a homogeneous mixture. Their individual properties may still affect how they interact chemically or physically.
A heterogeneous mixture is made of different substances that remain physically separate. A mixture of sand and sugar and a glass of iced tea are heterogeneous mixtures.
An example of a heterogeneous mixture would be water and flour.Muddy water, milk, paint: you can't see through!Saltwater and soda.
