Description
1982 SG X898 12½p light emerald (cb) and SG 907 15½p pale violet (2b) each with star underprint in vertical se-tenant pair, both with variety “phosphor omitted”.
The 12½p is listed at £70 (SG X898uy) but the 15½p inexplicably is not listed at all even though they exist in the same quantities. Scarce.
