If no owner appears within three months after such finding or saving and offers reasonable proof of his ownership, and compensates, or in good faith, offers to compensate, the finder or saver for the expense necessarily incurred by him, then such property vests in such finder or saver, unless it is of greater value than $20.00. If of such greater value, then he must publish a copy of such verified list for three successive weeks on the public bulletin boards in Agana and those nearest the place where the object was found, and if the owner does not, within one year after the completion of such publication, prove the property and pay, or in good faith, offer to pay all charges thereon, the title thereto vests in such finder or saver. If the finder or saver of property does not comply with the provisions of § 41502, or if, though he does so comply, he refuses to surrender the property to an owner who has made reasonable proof of ownership, and paid, or in good faith offered to pay, all legal charges thereon, he is liable to the owner for double the value of the property, and the owner may exonerate himself from all liability arising out of such property by surrendering, or offering to surrender it, in satisfaction thereof.
