25 Dollars - Elizabeth II Ayrton Senna

Ayrton Senna died at Imola on May 1, 1994 — a Sunday, during the San Marino Grand Prix — after his Williams FW16 left the track at Tamburello corner on lap seven. The crash triggered sweeping FIA safety reforms that reshaped Formula One infrastructure for the following decade.
