I am going through the Mason Cards I have and scanning them to a file for easy accesss.
So far I have found 3 cards without a name, address, or date of completion. It would be real tough to trace any of these chips. the cards do not even say which office of Mason they were shipped from. Mason had several offices from coast to coast!!!!

One more example of the Mason Co masking illegal operators or possibly just walk in business that laid down cash for the chips.

I have some cards from TR King that have no name or address and says right on them "Cash Sale"
