It is kind of funny. About a decade ago I was ordering some pop bumper caps from Steve Young and asked him if they were NOS or reproductions.
He said in a fun light hearted way (and if you know Steve that is rare) they are not NOS since the are still being made using the same original die mold, hot stamp, ... he said - "They are just stock".
(I'm sure he yelled at me for something else but he is the best)
