Abraham Lincoln 5 cents blue perforated 12 horizontally, very fine with copy 1991 Philatelic Foundation certificate (for pair), cat.v. $ 5750. These first government coils were an experiment, and collectors and dealers were generally unaware of their existence. Regular sheets of 400 were printed, then perforated in only one direction and then cut into strips of 20. The strips were hand pasted together to form rolls. As such, they are almost always strongly centered to one side.
