Given that the current bid is only about 20% of cat that's a pretty easy assumption.
Scott is $1,690. so double the current bid would be a low price for a collector to pay (a bargain). A dealer would pay that much I think. Any dealers wish to comment?!
How are you determining the CV for this? The closest item I see in Scott's 2014 US Specialized is a block of 12 with top selvage and plate numbers: $1,150 hinged, and $1,850 unhinged.
This item is hinged ("the center two stamps top and bottom with light hinge mark"), and lacks plate numbers and "TOP" markings (but does have a bottom centerline). It is a very nice piece, but if from my reading of Scott, I'd have a hard time guesstimating a CV of greater than $900. What am I missing? Is the bottom centerline sufficient to value it as a plate block? Even so, the fact that it is hinged should bring the CV down closer to $1,200, shouldn't it?
FWIW, it is now up to $420. Based on a CV, say, of $1,000 (to be generous), and that it is a fine specimen of a desirable stamp that should go for 60-70 percent of CV, were I sniping on it, I'd probably put in a last minute snipe of $700, and expect to have a good chance at having the winning bid. But, if I really, really wanted it, I'd probably double whatever is the current bid at the time of placing the snipe (i.e., if still $420, I'd snipe $840).
BUT...the two of you (revcollector and Bill Weiss) run rings around me in terms of knowledge and experience, so I must be missing something.
