"Who knows if Mr. Borland just picked up some left over blanks and had the company doing the work, run off the excess "Nevada" stock"

The company 'doing the work' as you put it, were Burt Co./Atlantic Standard. They made the blanks also. I doubt what you suggested happened or we would have seen more.

So far only one apparently genuine Borland 'freak' has been reported, Rick Miners $1 mint in black.
