This is the 4Ę Stagecoach coil issue from the Transportation series. Although these stamps look similar, there is an easy way to tell them apart.
Scott #1898A was issued in 1982. The inscription across the top, ďStagecoach 1890sĒ is 19.5 mm long. It spans almost the entire width of the stamp. There is only a little white space between the perforation holes and the start (or end) of the inscription.
The stamp was redrawn and issued again in 1986. This time, the inscription is only 17.75 mm long. Itís 1.75 mm shorter, which doesnít sound like a lot. But when you compare these two issues side by side, the difference in noticeable. On #2228, there is more distance between the perforation holes and the start (or end) of the inscription.
Another thing Iíve noticed is that on mint copies, the paper used to print Scott #2228 is whiter in appearance than the paper used to print Scott #1898A. Of course, this isnít as exact as measuring the inscription.
Both stamps are common. If youíre not careful though, itís easy to mix them up because they look so similar.
For collectors of errors, be careful. Both issues are known imperforate. Scott #1898Ad is the imperf variety with a Scott catalog value of $625. Scott #2228b is the imperf variety on the later redrawn issue and has a Scott catalog of just $200. Because the perforation holes are missing, itís important to measure the inscription. Make sure youíre buying a true #1898Ad, and not an imposter #2228b.
