Lead leaching from pewter
In previous centuries, the pewter used to make tankards often contained lead, which exposed the drinker to medical effects ranging from heavy metal poisoning to gout.[6] This effect was exacerbated in cider drinking areas such as Somerset, UK, as the acid qualities of the cider leached out the lead content from the pewter more quickly. Clay tankards became prevalent in this area. Pewter is now widely lead-free.

Is your Pewter lead-free?
Chances are you would be fine over the course of a single night anyway.
Don't do anything - go have fun!
