The first stamp was issued on July 1, 1847, in New York City. Boston received the stamps the next day.
A 5-cent stamp paid for a letter weighing less than 1 oz. (28 g) and traveling less than 300 miles; the 10-cent stamp was charged for deliveries to locations greater than 300 miles, or twice the weight deliverable for the 5-cent stamp.
