Coal hole. A name given to the basement of a former building at No. 23 William street, New York,
where calls of stocks were held and dealings conducted by outside brokers (brokers not members
of the New York Stock Exchange) in 1862 and succeeding years. These brokers had no
organization, but paid a fee to the owner of the building for the right to enter the Coal hole.
Reports, of their transactions, however, were printed in the newspapers under the caption "Sales
at the Public Stock Board."
