Next is AI generated as I wasn’t to familiar with British and IRA campaigns and items associated with them.
A Royal Marines General Service Medal (GSM) with the Northern Ireland clasp is worth generally £75 to £150 for unnamed examples, but can reach £300-£400 or more if named to a specific unit like the Royal Marines and in excellent condition, with named medals to highly experienced or casualty-linked individuals fetching higher premiums; reproductions are much cheaper, while value depends heavily on condition, naming, and specific unit. 
Factors Influencing Value
Naming: Medals named to specific service members (like Marine A. Heggie) are significantly more valuable to collectors than unnamed ones.
