OBVERSE

There is literally not a front and a back, but a side seen from the Moon and a side seen from Earth.

REVERSE

The reverse refers to a plan "seen from Earth". Indeed, the Moon is on the left and the astronaut is seen from behind. The inscriptions "1969-2019" as well as "50 years of the First Steps on the Moon" bear witness to the anniversary of this event. The face value is also visible on the reverse.
