The data consists of compiled public securities as listed in newspapers from the period 1786 to 1862; the full set of files cover a number of U.S. cities plus London, and among the areas covered is New York. The data is encoded as prices over a span of time (at the level of detail of year, month, and day) described here as a run. Issuers of the securities are named, and are grouped by commercial sector and company types. Data for New York alone can be downloaded, as can separate files for each city.
Unique variables include the company or issuer of a security (encoded numerically in this dataset).
