Yes and no, an editor from Woods Hole interviewed me first and sent a 1968 JFK half dollar for the reward. She wrapped the coin in some paper and sent it in an envelope (postage was $1.18). When it arrived, either a sorting machine somehow squeezed the coin out of the envelope or someone carefully sliced the envelope open and removed it. I suspect the latter!
So, no reward! Finding the bottle and the history was enough of a reward for me! It was neat to talk to this scientists grandson and granddaughter in-law over email! His grandson told me how he used to assemble these bottles for him, 1 cent for every 10 he completed! Some afternoons, he was able to make a dime!
