After breaking the bottle open, Winkler and her husband found a dateless postcard that offered a reward of one shilling to whomever returned it. Just so everyone is clear, one shilling is equal to five pennies, which is an indisputably generous reward.
The postcard also featured a message (in English, German, and Dutch), asking the bottle's finder to fill out information on where it was found, and to return it to the Marine Biological Association in Plymouth. The couple happily obliged, and, upon receiving the bottle, The Police's "Message in a Bottle," mysteriously began playing at the Marine Biological Association! What! There wasn't even an iPhone in sight! This part may not be entirely accurate.
The bottle was found to be one of 1,020 thrown into the North Sea by the association's former president, George Parker Bidder, between 1904 and 1906. Bidder was apparently trying to study the deep sea currents. But none of that matters, because the most important part of this story is that the couple was actually rewarded their shilling. They also may get into the Guinness Book of World Records, but, again, the single shilling is the only thing that matters here.
