1851 George Washington (originally 12 cents)

Several unusual aspects attract collectors to the George Washington stamp released in 1851. Although its original 12-cent denomination paid the way for certain heavy domestic letters sent afar, such use was uncommon. Envelopes bearing this Washington stamp tend to carry it in combination with other denominations or, more often, paired to cover the 24-cent rate for letters to the United Kingdom. © 2022 United States Postal Service®.
