If one gives money to a money changer, if it is not bound and sealed, the money changer is permitted to use it and is thereby responsible if the money gets lost. There is a debate whether the money changer is also responsible for oness (accidental damage). Regarding shlichut yad, if one decides to use an item they are watching and it then breaks, if the item changes in value from the time the shomer decides to use it until the time it breaks, what value is the shomer obligated to pay? Beit Shammai, Beit Hillel, and Rabbi Akiva have a debate regarding this issue. The Gemara brings five attempts, four of which are rejected, to understand the disagreement between Beit Shamai and Beit Hillel. According to the conclusion, the debate is not regarding a fluctuation in the market price, but the value of the animal itself increases or decreases by having offspring/wool to be sheared. According to who do we pasken?
