I found this amongst some pocket change . . . a new entry in the Lewis and Clark Westward Journey nickel series. According to the U.S. Mint web site, the design depicts a 55-foot keelboat with Captains Lewis and Clark in full uniform in the bow.
I can make this out on the enlarged image, but on an actual nickel — maybe it’s my failing eyesight, but the only feature I can see clearly is the sail, which to me looks just like one of those brontosaurus burgers that tips over the Flintstones’ car at the drive-in . . .
