Sayyiduna Ali bin Murrah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Whoever finds a trivial thing that has fallen, such as a dirham, a rope, or something similar, should announce it for three days. And if he finds something more valuable than that, he should announce it for one year.

Brief Explanation
Benefits: … Since this hadith is weak, it is not considered authoritative; therefore, the announcement should be made for only one year. However, there is no need to announce trivial items, such as a date seed, one or two rupees, etc.
