Which is an accurate observation? the coin shows that passing the peace pipe was an important tradition in 1621. the coin was minted in the year 1621. there is a woman’s face on one side of the coin. the coin shows that american indians influenced us history.

The question is basically asking which of these can be known by just looking at the coin. It cant be the last one because we don't have time to research about the influence Indians had on us history.  The first one is wrong because we are just looking at the coin, we don't know anything about it other than it's outside appearance. We are once again taking a look not studying the coin so we can eliminate the second one.  

There is a woman’s face on one side of the coin.  That is an observation, be cause its obviously presented. Observations are a crucial element when performing lab's in biology.

Hope I helped. :)
