The characteristic that ensures that money is free from forgery is its "legality." Legality means that the money is authorized by the government and has been issued by the central bank. This means that it is backed by the government and has a legal status as a medium of exchange. Counterfeiters cannot legally produce money, so they are not able to reproduce all of the features of genuine currency, such as the security features that are built into banknotes to make them difficult to copy. Therefore, by ensuring that money is legal, it helps to prevent counterfeiting and ensure the authenticity of the currency.
