Here are a few more shades that I've acquired of the 3c 1861. These came from Jack Daley, who has been very active on
ebay in the last couple of months offering shades of the 1861 3c. I've had some conversations with Jack via email, and he is extremely knowledgeable here, and his sales always include great images and information about the shades.
1861- Salmon Rose Pink (#64B, Rarity Factor = 4):
1861- Brilliant Rose (#65, Rarity Factor = 5):

1861- Salmon Rose (#65, Rarity Factor = 2):

AND not sure yet-- this is what Jack mentioned about this cover:
I originally identified this as #64b following a notation on the back of this cover that calls it "Rose Pink". It certainly is not an ordinary rose and is quite pink. On further study, I am inclined to classify it as a 'Pinkish Rose", a shade identified by Stanley Ashbrook (also referred to as 'near pink').
The telltale signature of pinkish rose is the blurring of the image, especially as seen in the demarcation between the edge of the three and the adjacent lattice work. This effect is quite pronounced on this specimen. This shade is almost always seen with a December usage - indicating it may have been a short production run designed to get back the the desired pink shade. Due to the poor performance of the ink - it's inability to honor design details - the experiment was quickly abandoned yielding a stamp rarer than the rose pink but not as scarce as the true pinks."

In any case, I really wanted it because of the date on the cover!
Good information--
Hope you enjoy-- Ray
