My knowledge of this series is sketchy because they rarely show up for sale in the UK. Based on the American comics' series, the UK editions published by Gerald G. Swan reprinted American material. Each issue was a different focus such as Archie or Jughead or Archie's Girls Betty and Veronica.
When they do show up for sale, VG copies are listed at around £20 and probably take an age to sell! A small collectors' market in the UK limited to those who remember them as children I would have thought.
Note: some PR issues may have no value. Selected issues in FN, VF or VF/NM may not exist in some titles.
