Grill (83 var). Beautiful deep shade, prominent grill clearly showing
the additional four vertical columns grill points at left, tied by
quartered cork cancel, "Richmond Va. Nov. 21" (1867) circular datestamp on
bright orange cover to New York City.VERY FINE. AN EXTREMELY RARE EXAMPLE OF THE PARTIALLY ERASED C GRILL VARIETY AND BELIEVED TO BE THE FINEST OF THE FEW KNOWN ON COVER.
In a few areas of the C Grill (Positions 99-100R, 89-90R, 79-80R, 68-69R and 1-2L, 11-12L, 21-22L and 31-32L), the points between grills were insufficiently planed away or erased when the A Grill was converted to the smaller C Grill. As a result, some of the stamps from the C Grill have grills measuring approximately 18 mm wide. These so-called Partially Erased C Grill stamps are very rare, and the cover offered here is regarded as the finest example of the few known on cover. It is also a very early use of the C Grill (EDU Nov. 16, 1867). The letter is written by a woman to a wealthy New York real estate developer, begging for money in a rather pathetic tone (yet she is articulate and includes a newspaper clipping about the addressee's major building projects in New York).
