I was born and raised in Delaware. I tend to collect Delaware items, especially the Tercentenary items that were issued with the 1936 Delaward commemorative half dollar. The celebration covered the landing of the Sweds in Delaware in 1638. Their ship was the Kalmar Nyckel which shown on all of these items. The commemorative half dollar The two Krona piece the Sweds issued with the half dollar, which is about the same size. A very nice silver medal the Sweds issued. I also have this in copper. I have not see a large number of these pieces. A medal that was issued during the celebration. I bought this piece for 50 cents on my 5th grade field trip. This is listed as a so-called dollar. There is a large version of it in copper and silver. The large silver piece is rare. I have only heard of a couple of them and have never seen one. The issue price was $7.50, which was a lot of money in 1938 when the country was just coming out of the Great Depression.
Something a little bit older... a well worn Roman Empire legionary Marc Antony as Triumvir & Imperator silver denarius from 32-31 BCE. The galley looks more like a centipede than a ship.
