I found about a 4 dollar pen half used in a public place,looks like it was there for a while before i found it. After i picked it up i noticed it has a name but with a last name like cohen in monsey it will be very time consuming to find the owner and likely he was miyaaeesh since it has been a while even though it has a siman. What should I do with this pen. Thank you
My assumption is that you found the pen in a place that is frequented mostly by non Jews. Therefore although the pen had a siman on it, the owner is still meyayish from getting it back, since he assumes that a non Jew found it and will not return it, therefore you can keep it.
