Lots of confusion abounds here when talking about UK editions.
Do you mean
a) A US comic produced and priced (Pence) for the UK market
b) A UK comic produced and priced (Pence) for the UK market
These are two totally different things and lots of people are confused by the difference.
Just to clarify further, as far as GA comics are concerned, there are extremely few examples of A) as U.S. comics were not distributed in the U.K. until November 1959.
And as far as B) is concerned, the black and white reprints that were produced exclusively for the U.K. market (mainly by L. Miller and Alan Class) that contained GA material have a very small fanbase, even in the U.K. Some of the reprints have the same covers and interiors as their U.S. counterparts, but not many. Hard to provide a proper rule of pricing for these books due to their being relatively few of them and the limited demand.
The pence / cents conundrum is very much a Silver and Bronze Age thing.
Thanks Andy, I tried to write something similar but deleted it as it didnt make much sense, unless you knew what I was talking about.
You put it so much better than I could
