[All quotations up to 1899 are from the Oil City Derrick; all quotations for 1900-1903 are from the New York Commercial.]

In the following table is presented the highest and lowest price of oil, the months in which these quotations occurred, and the general average for each year. The "average" as estimated is usually the mean price between the highest and lowest quotation of a given time. It is sufficiently accurate for general purposes of comparison. It would be an almost impossible task to determine a "true average" from the reports of the daily sales that are now on record. Previous to 1875 the quotations are given for points along Oil Creek, and they hardly represent what the producer actually realised for oil at the wells. From 1875 onward the trading in oil was placed on a more satisfactory basis by the general adoption of pipe-line certificates, and the exchange quotations show very closely the value of the oil at the wells. When the certificate was finally purchased by the refiner, it was subject to a uniform charge for pipage of the oil from the wells to the nearest shipping point.
