The Rare 2d Coil was an experimental vertical coil stamp, denominated 2d, issued by the Irish Post Office in 1935[2][3] and is one of the scarcest, and most valuable, Irish stamps. It is often referred to by stamp collectors simply as "Scott 68b" or "SG 74b",[1] being the Scott and Stanley Gibbons stamp catalogue numbers respectively.
