The commemorative 100 escudos coin issued in 1986 celebrates the 10th anniversary of the Azores’ Regional Autonomy. It is part of a series of regional coins issued by Portugal in the final decades of the Escudo currency and is of interest to both local and international collectors. The coin is relatively accessible, but certain versions (cupronickel circulation vs. silver proofs) attract different types of collectors.
Description and Historical Context
The Azores were granted political autonomy in 1976. A decade later, in 1986, this coin was minted to mark the 10th anniversary of the region’s autonomy. It is part of the series of commemorative coins issued by the Portuguese Republic to highlight regional milestones and national events.
Technical Specifications (Circulation Version)
- Face value: 100 Escudos (100$00)
- Year: 1986
- Material (standard circulation): cupronickel (Cu 75% / Ni 25%)
- Diameter: ≈ 34 mm
- Weight: ≈ 16.5–16.6 g

The obverse (front) shows the coat of arms and the inscription “República Portuguesa · Açores” with the denomination “100 Escudos.” The reverse features a design commemorating the 10th anniversary of regional autonomy, often with floral or ornamental motifs and the artists’ signatures.
Designers and Mintage
The coin’s design is attributed to Isabel Carriço and Fernando Branco, according to the Portuguese Mint (INCM) and commercial catalogues. The circulation cupronickel version had a mintage of roughly 750,000 pieces, making it relatively common.
In addition to the standard circulation coin, proof versions were issued (including some in 0.925 silver) and sold in presentation sets for collectors. These proofs are rarer and typically more valuable than the circulation coins.
Numismatic Value — Market Overview
Rarity and demand: The high mintage of the standard cupronickel coin makes it common in circulated condition, so its market value is generally low. Proofs and silver issues are more sought-after and command higher prices.
Indicative price ranges (2020–2025):
- Circulated coins (VF–F condition): generally €1–€5
- Almost uncirculated / mint state coins: typically €5–€15
- Proof / silver coins in original case with certificate: €30–€80, depending on condition and packaging
Note: Market prices fluctuate; for an accurate valuation of a specific coin (condition, case, certificate), consult auction houses, specialized shops, or recent sales databases (Numista, eBay, numismatic auction sites).
Collector Tips — Evaluating a Coin
- Condition: Check for scratches, wear on raised surfaces, and original luster. Condition greatly affects value.
- Case and certificate: Important for proof silver coins, increases value.
- Type (cupronickel vs. silver/proof): Verify metal content by weight and visual inspection. Silver proofs are worth more.
- Mint references: Check catalog numbers (KM#45) for accurate identification.
Conclusion
The 100 Escudos — 1986 (Azores) coin is representative of Portugal’s late Escudo-era commemorative issues: historically significant (marking 10 years of Azorean autonomy), easily obtainable in cupronickel circulation, and more valuable in proof or silver versions. It’s an ideal entry for those starting a Portuguese regional collection or completing a 100 Escudos series, with the potential for modest numismatic gain if a proof coin in original packaging is found.
