Scott,

I collect these stamps. As Pete has said, they are pretty tough to find, especially in nice condition. Many are found with back damage from having been mounted. Even some of the nicer ones I have seen are in lower grade holders presumably from paper loss on reverse. I have tracked them for a while and most players I have only ever seen 1-3 examples. There are many examples which I have not even seen an image. I have seen more Cobbs than any other stamp.

I know of a few other collectors of these. I believe one board member (who doesn't post too often) is at about 75% or so completion, which I think is incredible considering the frequency with which they appear. Good luck if you choose to pursue, they tend to get decent prices, especially for clean examples.

Mike
