What is the ruling on trading antiquities, especially ancient coins and statues? And what is the ruling on selling the head of a small statue that was found not to be owned by the seller? And what should be done with the money earned from this sale, knowing that the buyer is not a Muslim?

It is permissible to search for and excavate the wealth or belongings of disbelievers (kuffar) on land owned by an individual or on unowned land. One-fifth of what is found must be given out and spent in the categories of zakat, and the remainder becomes the property of the finder. There is no consideration for a law that prohibits this, but one should weigh the risks and harms resulting from violating the law against the benefits of extracting such wealth. It is not permissible to sell or trade idols (statues), and they must be removed. If the antiquities being traded are idols or contain symbols of disbelief, then one must repent from this act and spend the wealth gained for the benefit of Muslims. As for permissible antiquities, there is no objection to trading them, and their price must be paid to their original owner, or spent for the benefit of Muslims if the owner cannot be reached.
