A Dark Mark Token was a small green token imprinted with the Dark Mark. Given the symbolism, they were likely used by the Death Eaters for some purpose. Harry Potter, Ronald Weasley, and Hermione Granger found many of thse throughout the latter part of their Horcrux hunt (starting with the Skirmish at Malfoy Manor).
