Obverse Design Legend curving above says "THE . BRITISH . GLORY . REVIV . D . BY . ADMIRAL . VERNON". There is an inside line enclosing the legend, and proceeding under the platform as well. To our left is a ship heading to our left, away from Admiral Vernon. The bowsprit is pointing at the letter "I". In the center is a full length figure of Admiral Vernon with his body half turned to the right, and his head fully facing right. Vernon is holding a sword in his right hand and a baton in his left. To our right is a cannon with the mouth of the cannon pointing at the letters "RN". The cannon and Vernon are on a grained platform, and Vernon's feet are in in front of the trail of the cannon. Under the platform in the legend area are some ornamental leaves. The medal has a plain and smooth rim.
Reverse Design Legend curving along the top says "HE TOOK PORTO BELLO WITH SIX SHIPS ONLY". There is an inside line enclosing the legend. In exergue (under a line along the bottom of the medal) it says: "NOV . 22 . 1739". Under the date are some ornamental leaves. The center is the attack on Portobello. The six ships are lined up two in the top row and four in the bottom row. All are sailing right except the right-most ship on the bottom row, which is sailing left. There are no boats in the harbor. There is a steeple pointing at the letter "E", a spire to the right of the letter "O" and a tower pointing at the letter "I". The center tower on the mole does not have a flag, and the two flags on the left fort are weak. There are water lines though out the harbor. The medal has a smooth and plain rim.
Distinctions

There are about 41 varieties total with a ship, Vernon and a cannon in that order. Of those, 26 have Vernon standing on a platform. In nine of those the platform is grained. In five of the nine the ship is sailing to the left.

Moving to the reverse side, two of the five have the spires at "E", "O" and "I". Of these two, one has a flag on the tower on the mole, and this one does not. Also in this one the flags on the left fort are weak.
