Q. I also saw in the shul a two dollar coin on the floor. Since there is likely no simanim or marks that would be required for returning it to the owner, does one have to pick it up and apply effort and time to return it if possible to the owner, or can one just leave it there?
A. Horav Shlomo Miller Shlit’a opinion is that since it likely was in a distinctive place, that information could be used for a siman needed for the return to the owner, when possible.
