100 Lekë Albanian Railroads, Essai

Albania's railway network was almost entirely a post-WWII construction project, built largely through forced youth labor brigades under Enver Hoxha's regime. The 1988 commemorative program marked the expansion of the Durrës–Elbasan line, one of the few infrastructure achievements the isolated Hoxha government actively promoted abroad. Essai pieces — trial or pattern strikes produced for official review — were typically struck in very small numbers for the Paris Mint's own records and select government recipients.

KM#PE4 is among the scarcest Albanian gold issues of the period precisely because it never entered commercial distribution.
