The passage primarily explains that the silver coin is historical fake providing three theories which sustain the point. Whereas, the lecture deals with the explanations that many archaeologists support the genuineness of the coin by challenging the former theories given in passage.
Firstly, in the passage, it is mentioned that there was a great distance between Maine and Norse settlement. So, there seemed no connection of bringing up any coin traveling that distance according to the passage. However, the lecture clarifies the fact that traveling the great distance could be reasonable inorder to explore and obtain any interesting objects such as coin. This rules out the first theory.
Secondly, it is not necessary that Norse had not brought any silver coins with them. Because they were the explorers, they did not have permanent settlements, they could have packed of all the coins they had while moving. This contradicts the second theory that there were no other coins found.
Thirdly, it could be true the North American might not recognise silver coin as money. But they were always keen to have new interesting, valuable and attractive things with them. Therefore, Norse might had aimed to trade silver coins with them as those coins could be used in making necklaces, jewelry and so on. Thus, the third theory of Norse traveling to North America is justified by the lecture.
