May I ask the question?
How did a math teacher become the leading expert on coin mintage and machining?

Welcome to the forum!

It was a calculated move.

A calculated move? How so?

See I think certain definitions may be in error.....

As an example.....ALL errors minted on coins are "machine errors", other than over polished dies, other wise they'd be put there on purpose.....

I'm not reading this.....I worked in various machine shops, but not in the mint, and witnessed how errors happen....I've also read though, the definitions..,.it's my belief that all errors should have a designated value and that none should be designated "worthless" because it creates an ambiguous situation that lends to cheating people.....

The market already designates a value for minor errors and many times that value is 0. Why? Because collectors have no reason to pay a premium for them when they can be found in circulation for face value. Why would dealers pay a premium if there is no demand?
There is absolutely nothing wrong with searching rolls and collecting minor errors. Maybe calling them "worthless" is a little harsh, but saying they have "no added value" is factual and accurate

Value is a function of supply and demand.

Also, I don't know what s "machine error" is. I know what "machine doubling" is, and the term is quite appropriate.

The following site has an extensive listing of error and variety types broken down by minting and die making process steps. I think you'll find it very useful and it can probably help answer many of your initial questions
