NOVAE SUECIAE is NEW SWEDEN, or Delaware in the New World. SUECIA MEMOR means SWEDEN IS THANKFUL. The coin catalogs report that the spiffy square-rigged ship is the Calmare Nyckel.
This coin is a one-year commemorative (1938) celebrating the settlement of Delaware. It contains 0.386 troy ounces of silver. Base value (BV) is 0.386 times the current price of silver (see kitco.com). If silver is selling for, say, $15 US dollars per troy ounce, BV is 0.386 x 15 = $5.80.
Catalog values depend on BV, as follows:
average circulated: BV + $5 US dollars approximate catalog value
well preserved: BV + $10
fully uncirculated: BV + $20
