What would you do about this??

the_tired_one

I would contact them again - to clarify how they expect to receive the items and explain that a 'non-reply' will lead to their bid(s) being cancelled (and I would put them on my block list also)

Contains_Mild_Peril

I concur with the_tired_one's advice.

I figure if I was that worried about a genuine note (a not very well produced one) then a fake would stand out a mile. Apparently it's all about the feel of the paper... and if you can tell a fake from a real note by glancing at it from one metre away, the fakes must look WELL ropey.

Fakes come in various qualities, but the hardest part to fake is usually, as you say, the texture of the paper. It's a unique type of paper used only for banknotes, whose "recipe" is a closely guarded secret.
