It seems to me there is a significant difference between an entire run of chips that have a mistake in them, such as a misspelling, and a single or small set of chips that contain an error not made on the vast majority of chips manufactured at that time. I don't find it helpful to label them in the same way since the first is just a rack chip where someone blew it somehow and the other where the value of the chip may be effected by a rare difference from the standard rack chip.

Does anyone else agree? Does anyone have any suggestions for how we can differentiate between the two in how we refer to them?

Great observation, Jo, by the way.
