The Euro symbol (€), supposedly but not certainly designed by Alain Billiet, was selected from a pool of proposals. According to a very official-looking document from :
Some thirty drafts were drawn up internally. Of these, ten were put to the test of approval by the general public. Two designs emerged from the survey well ahead of the rest. It was from these two that the President of the Commission at the time, Jacques Santer, and the European Commissioner with responsibility for the euro, Yves-Thibault de Silguy, made their final choice.
The BBC writes that the runner-up design is now "all but impossible to trace". However, if the above is true, members of the public saw nine alternate designs, one of which they considered acceptable. Perhaps the survey conducted was small, but unless respondents had to sign nondisclosure agreements, information about it may survive. What were the nine other designs?
