In theory, as its density is 19.1g/cm3, which is approximately 70% denser than lead, uranium could be used as material of making fake coin. However, it is weakly radioactive and not as dense as gold, so it does not appear to be a practical method.

Then people have discovered that tungsten is environmental-friendly, durable and hardness, the most important is that its density of 19.25g/cm3 is just about the same density as gold (19.3g/cm3), which bears the similar specific gravity. These advantages make tungsten enjoys the superiority to be the best substitute for the costly metal of gold or platinum. It is necessary to tell that alloying gold with tungsten would not work for several reasons but a coin with a tungsten center and gold all around it could not be detected as counterfeit by density measurement alone.
