20 Millimes (magnetic) - Tunisia

A relic of the medieval era, the 20 Millimes (magnetic) - Tunisia from Tunisia (1428–2017), denomination 20 Millimes, offers collectors a tangible link to a world of knights, merchants, and pilgrims. Struck in steel or iron, this coin reflects the material constraints of its era. Steel and iron coinage became common during periods of precious metal shortage — wartime rationing, postwar reconstruction, or economic crises — when governments needed to maintain coin production at minimal cost. These utilitarian pieces have their own historical significance and can be surprisingly difficult to find in uncirculated condition. Collectors seeking to add this coin to their numismatic portfolio should prioritize condition and authenticity. Professional grading by NGC or PCGS removes the subjectivity from condition assessment and provides certified authentication — crucial in a market where counterfeits and artificially enhanced coins are an ongoing concern. Original surfaces command a significant premium over cleaned or polished examples. Storage in inert holders within a stable, climate-controlled environment is recommended.
