Funky double stamped Craftsman socket

[Zeeman]

I was organizing some of my flea market finds, and came across this. If it was an old coin, I would retire!
Anyone else have similar sockets or tools with mistakes in the stamping?

Don't have any like this myself. There was a snap on stamped upside down on here the other day.

First one that I have ever seen

^^ That means it's double super secret rare, right???

post it on Ebay and some fool will probably pay you big money for it.

I have a double stamped one somewhere in my stash of sockets.

I have had a few double or incorrectly stamped tools in 50 years. A not uncommon occurrence in mass production.

When I bought all the bolts for a R&D facility I would occasionally come across bolts without threads or bolt heads without the shank, it happens.

I bought a set of SK 1/4" deeps. The 13mm was totally unstamped. It was along time ago. I still have the set.

Thanks guys. I thought mis-stamping might be fairly common, but I figured quality control would have caught them. Could someone have taken these from the factory and put them into their own tool box? Or, was quality control just lax?

A modern production facility isn't going to check individual socket labeling for defects. They might pull a sample set off the line a few times per shift to check for systemic problems but that is about it.

I worked in R&D for disposable diaper processes and equipment. We use to constantly check by pulling samples off the line but there are hundreds if not thousands that go by while a sample is checked. The object is to keep the product within an acceptable range of variables. Today most of the QC is done by high speed cameras instead of physically pulling samples from the line although they do still pull samples at prescribed intervals that are sent to the QC lab for a complete evaluation.

It's also worth reading up on the history of Student's t-test. It will make you thirsty.
