All coins have a specific weight which you can find in coin referencing material per country along with a specific diameter. For example an U.S. 1922 Saint Gaudens Double Eagle ($20 gold piece) weighs 33.436 grams which contains 90% gold. If a coin is not this exact weight and diameter from this specific year then it is not the gold coin in question.
If you are not concerned about defacing the coin there are gold testing kits available online or at your local chemical stores. Most use Nutric Acid and Muriatic Acid, which are applied to filed particles from the specified coin. These acids cause non gold particles to separate from gold.
There are also electronic gold testers available at rather investment grade pricing.

How do you know if a half dollar California gold coin is real?
The best test is density, since a fake coin can still have a real gold plating over a base metal interior. Gold is denser than any other commonly available metal (there are denser metals but they are even more expensive than gold, so they would never be used to create counterfeit gold coins). You can measure the weight of the coin on a scale, and the volume can be determined with the use of a graduated cylinder (to measure how much water it displaces) then you can calculate the density, which is simply weight divided by volume. Compare this to the density of gold. If it's pure gold, the coin is real.

Is 2 dollar coins real gold?
You need to be more specific on the date of your coin and the country of origin. For example, some $2 coins are real gold, such as the Newfoundland 2 dollar gold coin which is 22K gold. On the other hand, there are many $2 coins that aren't real gold, for example Australia's modern $2 coin looks golden but contains no real gold, neither does Canada's modern $2 coin. If you are unsure about if your $2 coin contains gold, post a new question including the date and the country of origin.
