Useage
The eight cent denomination was issued primarily to care for the payment of registration fees and also for letter postage in excess of three ounces.
The Watermark
The watermark consists of single lined USPS letters. A stamp may show only part of a letter or letters
A new use
The discontinuance of distinctive Parcel Post stamps brought this value back into general use and it was issued in constantly increasing quantities. Two different imprints are found on the plates used for this stamp, " Imprint, A and plate number" and "A and number" only. Both of these had 2.75 mm spacings and there was no difference in the appearance of the stamps. The use of the imprint "Bureau of Engraving & Printing" was discontinued on later plates as an unnecessary expense
