Introduction
The 20 réis coin of 1892 belongs to the bronze series struck during the reign of King Carlos I of Portugal (1889–1908). It is a common circulation coin among collectors of Portuguese monarchy issues, valued mainly for its state of preservation and certain minting variants (notably pieces struck at the Paris Mint).
Physical and Artistic Description
- Metal: Bronze
- Weight: Approximately 12.00 g
- Diameter: 30 mm
- Edge: Plain (smooth, unreeded)
- Obverse: Bust of King Carlos I facing right, with the legend “CARLOS I REI DE PORTUGAL.”
- Reverse: The denomination “20 RÉIS” centered, often surrounded by a wreath — a design typical of contemporary small bronze denominations.
Aesthetically, it is a simple, functional coin, yet interesting for collectors building complete series by reign or type.
Historical Background
Issued during the reign of King Carlos I, this coin reflects Portuguese pre-Republican coinage, preceding the establishment of the Republic in 1910.
Some 1892 pieces were minted abroad, notably in Paris, and are identified in catalogs by mint marks. These variants may display slight engraving differences and are sometimes more sought after by collectors.
Mintage and Variants
Catalogs and auction houses report high mintages, which explains the relative abundance of this coin on the market today.
However, mintage figures vary depending on source and variant (Portuguese vs. Paris Mint). For example, some references list around 15,411,000 pieces, while others mention approximately 13,505,808, depending on the variety and year grouping.
When assessing rarity, always verify the exact variant — including mint marks and possible overstrikes.
Condition and Rarity
As with most circulating bronze coins, surviving examples often show moderate to heavy wear.
Coins in Very Fine (VF / MBC) or better condition are less common, and uncirculated or prooflike specimens (with original luster) can be quite desirable.
Certain variants — such as the “A” mint mark (Paris) — may also command higher interest and value.
Numismatic Value — Market Expectations
Market value depends strongly on condition and variant:
- Common circulated pieces (Fine to Very Fine / BC–MBC): typically €1–€10.
- Better preserved examples (VF–XF): can fetch €10–€50, depending on quality and appearance.
- Rare, proof, or high-grade (MS/UNC) examples, as well as distinct mint variants, can be worth significantly more, though these are rare for this specific issue.
Note: Marketplaces such as OLX, eBay, and numismatic shops show wide price variation — the actual selling price depends on demand, shipping costs, and auction fees.
How to Evaluate Before Buying or Selling
- Identify the variant: check for mint marks, overstrikes, or other distinguishing features (e.g., Paris Mint coins may show subtle design differences).
- Assess condition: focus on the king’s portrait relief, the clarity of the inscriptions, and the sharpness of “20 RÉIS.” Use standard grading scales (Fine, VF, XF, UNC).
- Color and patina: a natural, even patina is desirable; harsh cleaning significantly reduces value.
- Compare real sales: consult online catalogs, auction records, and numismatic dealers for recent market values.
Conclusion
The 1892 20 réis coin is an affordable yet historically appealing piece for collectors of Portugal’s monarchical coinage.
Its numismatic interest lies mainly in preservation quality and minting variants.
While most specimens have modest value, well-preserved examples or rare variants can command notably higher prices, making it a rewarding coin for both beginners and experienced collectors.
