Good topic. Here's a Greece 1 and 50 drachmai, and a Spanish 50 centimos which, while it doesn't have a ship, does have an anchor.
Here's three from the great seafaring nation of Portugal. The big one is 50 escudos. The denominations on the others confuse me.
And last but not least, a 50 cent Endeavor commemorative from New Zealand, 25 cents from the Bahamas and 25 cents from the British Caribbean states.
Ships representing the state, with the monarch also: A noble of 80d from the reign of Edward III of England - minted ca. 1363-5.
Most in the US will recognize this first one from circulation. The second is one of my favorite silver rounds.
A couple of hundred years younger, and a bit of an anachronism whence it was released in minisculity: This is a Scottish noble, one of the very very few ever issued from the reign of James VI in 1588. By this time the noble had been largely consigned to history. Notice the ship, but curiously the Scottish arms instead of a portrait of the monarch.

As far as circulation coins are concerned, we have these. The "reddish" pieces are the (country specific sides of the) Greek 1, 2 and 5 cent coins. The "yellowish" one is what is on the three mid-range (10/20/50 cent) coins from Cyprus. Christian
And here are two German collector coins. One shows a Hanseatic League "cog", the other depicts the current "Gorch Fock" vessel. Christian
