Tessellate S.T.E.M.S - Computer Science - School - Set 1 - Problem 1

In a cave, an archaeologist finds three chests: one labeled "Gold Coins," another "Silver Coins," and the other "Gold and Silver Coins." He knows from archaeological records that each label is written correctly but put on the wrong chest.

To figure out which is which, he may open a chest of his choice and take out a coin to see if it is gold or silver. However, because he does not want to mess with the historical setting, he is going to do this as few times as possible.

What is the minimum number of coins he needs to take out in order to figure out which chest is which?
