Q. I found money in shul, that looked like someone had it in their pocket and hid it before Shabbos, then forgot to come back and retrieve it. I put up a sign that it was found. How long do I need to keep up the sign? If no one calls at that point may I keep it?

A. Horav Shlomo Miller’s Shlit”a opinion is that it should be advertized for at least three weeks, (preferably three months) and then if there are no claimers one may keep the money.
