aaaaaaaaand it's gone.It comes up quite regularly on eBay. Rarely goes over $10-15 a puck. Bowls can command $25-50. Search for "Vintage shave soap" and "Vintage Shaving Soap".
The thing to be careful of with the boxed pucks is plenty of people sell modern formulation as vintage. Don't make the mistake of paying $15 for a $1 puck of soap.
Right now there's an unused currier and ives (williams) bowl that I've been resisting for the past month @ <$30 shipped. I've got a couple already and I can't say anything performs better.
Couldn't help it. Messaged the seller asking if he'd take $20, and he said yes.
But goes to show ya... the fact that an unused bowl of literally the best shaving soap ever made sat there for weeks @ $25 and sold for $20 says to me "don't compromise"... unless I guess you absolutely MUST have scent in your soap and can't figure out how to add it yourself.
