A classic gold coin that has been around for 400 years.
The technology of that time was groundbreaking. The coin is extremely thin, making the work of counterfeiters difficult. You can’t put anything inside the coin. Production outside the mint leads to the image on one side being visible on the other side. There are practically no forgeries.
Low weight means easy selling.
