Bava Kamma 62: Hidden Responsibilities and the Penalties for Theft

The case of one who gives a gold coin to a woman, and tell her that it is silver - what is she obligated to pay if it's damaged? Or lost or stolen? Given that she has no idea that the coin is gold (maybe she wouldn't have agreed to watch over a silver coin). Plus, some confusion by Rav about R. Yehudah's teaching. Also, 2 new mishnayot, one to end the chapter, and another to begin the new chapter. Reconnecting to Chanukah candles and the damage caused by fire - flax on a camel and a shopkeeper's Chanukah candles, as is mentioned earlier in Bava Kamma too. And the opening of Perek HaMerubah - the penalties for stealing an item, for damaging after theft, and when those penalties are not put into play.
