Voldemort bestowed the Dark Mark on only those in his inner circle.
[Fenrir Greyback] might be allowed to wear Death Eater robes when they wanted to use him, but only Voldemort’s inner circle were branded with the Dark Mark: Greyback had not been granted this highest honour.

But did Voldemort himself have a Dark Mark? He puts his wand to Wormtail's Dark Mark to summon the Death Eaters in Goblet of Fire, which suggests he does not have a Dark Mark. On the other hand, he stated in Goblet of Fire that he and his Death Eaters were reunited under the Dark Mark when Voldemort was returned to his body.
‘Welcome, Death Eaters,’ said Voldemort quietly. ‘Thirteen years ... thirteen years since last we met. Yet you answer my call as though it was yesterday ... we are still united under the Dark Mark, then! Or are we?’ [dramatic gopher]

This could be referring to the Dark Mark that comes from Morsmordre (the Dark Mark in the sky), although nobody casts Morsmordre at the graveyard the night Voldemort is resurrected. Further, Voldemort had to have a way of summoning the Death Eaters to him when he is alone. How would he do this without a Dark Mark? Did Voldemort have a Dark Mark? If not, how does he summon his Death Eaters when alone? I'm looking for a canon-based answer, meaning no Wikis/Wikias -- only the books, Pottermore, or information from J.K. Rowling.
