This is a 1991 circulation issue 200 Escudos coin from Portugal, notable for being a bimetalic currency piece prior to the adoption of the Euro. The coin features a distinct dual-metal construction consisting of a nickel-silver center disk surrounded by an outer aluminum-bronze ring. On the obverse shown, the center contains the Portuguese coat of arms above the numerical denomination '200' and the word 'ESCUDOS' in capital letters. The outer gold-colored ring is inscribed with 'REPUBLICA PORTUGUESA' and the mintage year '1991'. Physically, the coin has a diameter of approximately 28mm and a reeded edge. The condition appears to be 'Circulated' (VF to XF grade), exhibiting visible surface micro-scratches, minor contact marks (bag marks), and a light layer of oxidation/patina, particularly on the brass outer ring. There are no signs of major structural damage, bending, or deep gouges. The striking quality is characteristic of late 20th-century mass-production minting, with clear legibility of the serif typeface and fine details within the shield of the coat of arms.

I have examined the digital representation of the 1991 Portugal 200 Escudos bimetallic coin. The specimen appears authentic, displaying the correct bimetallic construction (nickel-silver center and aluminum-bronze ring) and characteristic striking patterns of the Imprensa Nacional-Casa da Moeda. The condition is consistent with 'Very Fine' to 'Extra Fine' (VF-XF) circulation wear; I observe typical contact marks and surface abrasions, particularly on the softer outer ring, which shows light atmospheric oxidation. Since Portugal minted 21.5 million units in 1991, this is a very common issue without inherent rarity. Current market demand is driven primarily by world coin collectors and those completing denominations of pre-Euro European currencies. The value of this coin has largely decoupled from its original face value (approximately 1 Euro) and now reflects a nominal premium for its historical context and bimetallic appeal. Factors such as the absence of errors or exceptional luster limit its ceiling in the secondary market. Limitations: A definitive assessment of metallic density, weight (standard 9.8g), and edge reed consistency cannot be completed via photography alone. Full authentication would require a physical inspection to rule out counterfeit plating or weighted cores and to confirm the absence of deep cleaned surfaces hidden by photographic lighting.
