| 表面の説明 | The copper-nickel centre features a detailed architectural rendering of the Gothic Town Hall of Brussels (Hôtel de Ville), depicted in three-quarter perspective with its soaring central belfry tower dominating the field; the date 1997 appears to the left of the building, with the mint mark G to its right. The brass outer ring bears four heraldic shields alternating with the multilingual trial legends PRUEBA, TRIAL, ESSAI, and PROBE arranged around the circumference, with the trilingual country name BELGIË-BELGIQUE-BELGIEN inscribed along the lower arc. |

| 裏面の説明 | The copper-nickel centre depicts a draped, bearded male figure seated facing right on a plinth, rendered in a classical allegorical style, positioned before the large numeral 1 which serves as the denomination indicator; diagonal engraved lines radiate across the field behind the figure. The word SPECIMEN appears within a cartouche on the plinth beneath the seated figure. The brass outer ring displays twelve five-pointed stars of the European Union arranged around the circumference, with the letter E positioned in the upper field of the ring. |

Belgium struck a series of euro probe pieces in 1997 as part of the technical validation process required before eurozone production began. These were not public issues — they circulated among central bank engineers and mint technicians to test planchet tolerances, vending machine sensors, and automated sorting equipment across participating countries. The 21-gram specification on this piece differs from the final production standard, making it a measurable artifact of that calibration phase rather than a collector fabrication after the fact.
