#201 is the first issue of the Judge Dredd Megazine (which we will call Volume Five) and the first issue (since 1992) to use the original numbering.
Shades of American comic book culture creeping in here. They realised issue #18 of Vol 4 would in fact be the 200th issue of Judge Dredd Megazine published so to show its longevity and presumably quality, why not celebrate it by calling the next issue #201!
Note: some PR issues may have no value. Selected issues in FN, VF or VF/NM may not exist in some titles.
