Please rephrase question, the term 'ms stamp' means nothing in numismatics
In average condition, both coins are only worth their face value.
President Bush is not on a US coin.
A 2005 US nickel that has Ocean in View on the back is an ordinary coin from the Westward Journey series. If you found it in change it has no added value. A nice uncirculated one might retail for 50 to 75 cents.
The 2005 first class rate was 37 cents. The cost of a post card was 23 cents.
Please check your coin again and post a new, separate question.Liberty nickels were minted from 1883 to 1912There US has never made a gold nickel.
If you mean one of the 4 Westward Journey nickels dated 2004 and 2005 it's a novelty item that has no numismatic value at all. But it's still a nickel.
The stamp has to be accepted where you mail the letter. If you are mailing in Canada, you need a Canadian stamp. If you are in the US mailing to Canada, you can use a US stamp.
The nickel wasn't first minted until 1866. If the date 1805 is right after the names Lewis & Clark, and the other side shows President Jefferson, then it's a 2005 Westward Journey nickel, worth 5 cents.
The diameter of a US nickel is 0.835 inches.
In the US, a nickel is worth 5 cents.
Since 1938 the US nickel has had a picture of Thomas Jefferson on the front. The back side has featured a picture of his house, Monticello, for all years except 2004 and 2005 when four special designs were used in honor of the Lewis and Clark Bicentennial.
If it is a US nickel, it is 25% nickel, 75% copper. If it is a Canadian nickel I believe it is 100% nickel.
