$10, plus whatever shipping is. Found these while going through my toolbox looking for a hex driver. I honestly can not remember where I got these. I think I found them out in Willsboro, NY at a rummage sale where the owners of the old high school were selling off lots of laboratory equipment from the science lab. The school dates back to about 1920. Picked up a few very cool Geiger counters and lots of vintage test tubes and burets. Like I needed them.

Such it is collecting old stuff.
Got an electric Graphophone or Class M coin-op in need of posts? Caller #1 gets them.
