Indian Penal Code, 1860
Section 237
repealedImport or export of counterfeit coin
Whoever imports into India, or exports therefrom, any counterfeit coin, knowingly or having reason to believe that the same is counterfeit, shall be punished with imprisonment of either description for a term which may extend to three years, and shall also be liable to fine.
Why this exists
Counterfeit coin often crosses borders, either being smuggled into a country to be passed off as real, or made in one place and shipped elsewhere to avoid detection. This section targets the cross-border movement of fake coin itself, complementing the earlier sections on manufacturing and possession, so that customs and border enforcement have a clear criminal basis to act against anyone knowingly moving counterfeit coin across India's borders.
