Does the coefficient of restitution depend on the collision being performed?

Consider two masses ##m_1## and ##m_2##. They are placed on a frictionless horizontal table and ##m_1## is given an initial velocity, collides 1-dimensionally with ##m_2##, and the coefficient of restitution is calculated from the initial and final velocities.

If instead I had ##m_2## on a table and ##m_1## was dropped from a height ##h_i## onto ##m_2##, and then came up to a height ##h_f##, would the calculated coefficient of restitution be the same here as in the first situation?
