I'm betting it's regular old aluminum wrap, and not edible. I was just pointing out that edible precious metal foils were available during that era. Just not for lining pans. ;)

BTW, using those super-thin precious metal foils is a serious PITA. I generally use a damp artist brush to apply them, since they tear so easily.

Gold is used for edible art today too. Today we know that silver foils are poisonous, regardless of whatever King Louis’ physicians might have believed. Aluminum (but not as thick as Reynolds wrap) would be an OK substitute.
