Not being a collector of coins, there is no good reason why I should have noticed that the 2005 nickel had a different scene on the back. Instead of what I thought should be a view of the Capitol building, there was a seascape.
When I tried a magnifying glass on the coin, it did prove to be a seascape. It turned out to be part of a Westward Journey nickel series - information provided by Google.
That domed building on the reverse side of our usual nickel? It is not the Capitol. It is Monticello.
