Hi,
Long time listener, first time caller:- been collecting forever, recently started looking at the value and or rarity. Very unfamiliar with terminology...
Found this 1986 set of 10 Ciskei Edmund Halley (Halley's Comet) stamps with this "blob" on one stamp (on edge of the globe, below left of the "1". Does anyone know what this is or if it has any relevance?
comments much appreciated.
Thanks!
