M. F. Smith was the check manufacturer, not the mine company. Some of them had the cast number chisled off and another number stamped on the check. The reason for this is when a miner would come to work at the mine and he had checks from a mine he worked at previously, if the employee number was already in use he could not use them as is. So it was either buy a new number set of checks from the “company store” or improvise. To save money they would chisle the old number off of all their checks and stamp them with a new employee number not in use at that mine. Each set of checks would number 10 to 20 checks.
