From Scouting New York:
These thirteen slabs are stone samples, from which the primary building material for Grand Central was chosen. The samples were brought to New York City to test how they withstood the elements, though ultimately cost proved to be the deciding factor. Indiana limestone, the second sample in from the south, was chosen because it was the cheapest to transport.
