Found a 1893 library ledger that says rebinding cost 28 cents, blew my mind

I was poking around the Ohioana room at the Cleveland Public Library last week and the archivist let me flip through a repairs ledger from 1893. Right there in pencil it shows a full rebind on a worn out novel costing 28 cents, and the library charged the borrower 15 of that back. I sat there doing math on my own last clamshell case, linen thread and all, and it came out around 40 dollars in today's prices. So folks a hundred and thirty years ago had about the same trade, just way cheaper glue. What do you all charge for a basic rebind now, and does anyone know what a binder's hourly wage looked like back then? I'm curious if 28 cents was fair or a rip off.
