In the overall scheme of my life & loves, it's not important at all !
However, in the context of the comic hobby which I love and spend many hours researching etc I do feel that many of us are trying to right a historical wrong - in that for many years comics with pence prices were considered "reprints" and somehow inferior - the actual truth, is that they are first prints too (same American presses, same time) and ironically, almost certainly much, much rarer than their American counterparts (silver and early bronze at least)
There is no campaign to make the hobby think they're better than cents or worth more than cents, simply to say "this is the reality" - then people can be better informed, and the market will repond accordingly (and has done)
Pence keys in high grade are seriously rare - I only wish I'd bought more even 5 years ago, never mind back in the 80s when you could get a pence AF 15 for £200 (!)
While factually and logically, they are PENCE PRICE VARIANTS, CGC calling them "UK Editions" is not a big deal. But it is inaccurate.
(Graded UK only original-material comics like Cap Britain and Marvelman are also called "UK Editions", which adds to the inconsistency)
