the partially-erased grill variety was created by insufficient erasing or

2c Black, D. Grill (84).
Bottom sheet margin, original gum, clear and sharp grill points with second
impression of grill in selvage, centered to rightVERY GOOD. A RARE AND PRESENTABLE ORIGINAL-GUM EXAMPLE OF THE 1868 2-CENT D GRILL.
The device equipped with the D Grill was refitted with the E Grill on or about February 9, 1868. Based on the earliest known usages of the 2c D Grill (2/15/68) and 3c E Grill (2/12/68), it is our theory that the conversion from the D to E Grill took place only a day or so after sheets of 2c stamps were first run through the D-equipped machine. The great rarity of 2c D Grills, relative to all other regular-production grills, bears out this theory.
