The mid-December Siegel auction entitled “Important and Superb United States Stamps” was really worth observing. I did not bid myself, having just purchased a very expensive collection. However, I was really interested in seeing what would happen with the stamp on the cover of the auction catalogue. It was a very rare Scott 85D, the 10c green “Z” grill shown below.

The “Z” grills are some of the rarest of US stamps and 85D is no exception. The Siegel census reports that only 6 exist. One is in the New York Public Library collection and the whereabouts of 1 is unknown so possibly only 4 are available to collectors. All 6 known copies are illustrated in the Siegel auction catalogue and of the 6, I would judge this to be 3rd best. There are two lightly struck very fines that have superior centering and are sound, this one being fine. The Scott catalogue values the 85D at $225,000 with the value in italics, indicating that there is not a lot of sales data. The one in the Siegel auction realized twice that number….$550,000. Wow!
A couple of comments on grills. The “Z” is actually very easy to identify. The most common grills are asymmetric pyramids with the long axis vertical. In the “Z” grill the long axis is horizontal. I see a fair number of fake grills. They are fairly easy to spot with a 10X loupe. The pyramid shape should be clearly visible. Most fakes are square or round and lack the pyramid shape. Also, always be suspicious if the stamp is of exceptional quality. Grilling weakened the paper and so many grilled issues have a variety of faults, with thins in the grills being very common.
Clearly the 85D sale made the auction a huge sucess for Siegel. How did other issues fair in this period of economic concern? Below I show a few lots selected at random.

Scott 84, a Blackjack with D grill. Graded 70 by PSE, which for this issue is a very high grade with only 3 grading higher. Sold for $2000 against a Scott of $4500….a pretty low realization.

Scott 71, a stamp rarely found with the perforations clear of the design and graded by PSE as a 90 extra-fine and completely sound. Sold for $325 against a Scott of $200.

Exceptionally well centered Scott 90 with a nice strike of the California cogwheel cancel. Only graded as a 90 by PSE, probably because the PSE grading system downgrades for cancels that impact the design. However this is a beautiful stamp and sold for $2500 against a catalogue value of $600.

Scott 285, a gem stamp grading as 98, the highest grade awarded to a 285. This stamp sold for $3000 against a Scott of $80. Though this seems like a very high price, the Stamp Market Quarterly values a 98 at $3450 so this is over 10% below the most current SMQ. In the last few years, 98’s have been routinely exceeding the SMQ values so this might be considered a low realization…except that the population report indicates that there are 11 know 98’s. So the fairly high population report seems to have prevented this from a higher realization.

Shown above is a MNH 292 in the grade of fine with a catalogue value of $3900. It sold for $900.

The 292 shown above graded 95 extra-fine superb MNH. There are only 5 that have achieved this grade and none grade higher. It sold for $47,500!!! Clearly the market for highly graded stamps is doing okay even during this period of economic turmoil.
