Is it permissible to give money to a person who claimed ownership of it without objection from others?

This money found by the questioner is considered a luqatah (found item), and she must announce it for a year in the place where it was found. The questioner should not describe the money, but rather say: "Whoever lost something." She made a mistake by giving the money to the person she found near it without asking him for its description. Now, she must announce the money for a year. If its owner is found, she should retrieve it for him from whomever possesses it, if possible; otherwise, she should pay him a similar amount.
