i think you are trying to compare the terms "countermark" and "counterstamp" and i find that in use they can be used interchangeably......as a side note i find that countermark is used more on non-US issues while counterstamp is predominantly domestic

i believe that i once read that *mark would be struck obverse and reverse while *stamp would be only on one side (but i have seen so many diversion from this rule that it is hardly worth mentioning)

Countermark is used to denote an officially issued counterstrike.
Counterstamp can be made by any old body.

I guess the countermark would be the impression made by the counterstrike.
