OMG, he looks like a Vorta from the Deep Space 9 Series... 😮

My guess is that he inscribes another coin hidden in the pad, writes the numbers then exchanges the coins before the reveal.

[@Mister_Clipster]

Yup, I agree.

He writes on another medallion on the pad and in 2:10 he switches the medallions.
