Baldwin's Blog Explains the Silver Tetradrachm of Alexander the Great
On February 18, 2025, the coin dealer and auction house Baldwin's published a blog post on the historical background of the silver tetradrachm from the era of Alexander the Great, king of Macedon. The post describes the coin as weighing roughly 17 grams and as one of the most common and influential coins of the Hellenistic world. It gives no prices or details of any specific coin offered for sale.
Correction (Oct 13, 2026): We rewrote the headline, summary and body to match the source. We removed unsupported claims about Asia-Pacific wealth driving demand, six-figure prices and price ranges, forecasts of price appreciation, statements about investment, portfolio diversification and hedging during economic uncertainty, storage advice and blockchain provenance, aligned the English description of the coin designs with the source, and made clear that the source is a general explainer posted by Baldwin's on February 18, 2025. The previous headline was "How Alexander's 17g Tetradrachm Unified an Empire with Art and Propaganda."
This article is based on a post published on February 18, 2025, on the blog of the coin dealer and auction house Baldwin's. It is a general explainer and does not report the sale or price of any specific coin.
Alexander the Great and Macedon
According to the blog, Alexander III, better known as Alexander the Great (356-323 BC), took the throne of Macedon after the assassination of his father, King Philip II. The post says that under his rule Macedon grew from a regional power into an empire that stretched from Greece to Egypt and into the heart of Asia.
The blog says Alexander's conquests toppled the Persian Empire and spread Greek culture and ideas beyond their traditional boundaries. It adds that Hellenistic culture, which blended Greek, Persian, Egyptian and other traditions, influenced art, architecture, philosophy and coinage.
The Silver Tetradrachm
The blog describes the silver tetradrachm as one of the most common and influential coins of the Hellenistic world. It weighed roughly 17 grams, with slight variation by mint, and served as a major unit of currency and trade throughout Alexander's empire.
Obverse and Reverse
According to the post, coins from Alexander's era typically feature his portrait, often idealized to stress heroic and divine associations. In some issues he is shown with a lion skin or other imagery linking him to the hero Heracles, symbolizing strength and legitimacy.
The reverse, the blog says, often carries symbols of gods such as Zeus or Athena, eagles, or other emblems that underscore the divine favor and authority under which Alexander ruled.
A Tool of Authority
The blog states that beyond their economic function, the coins were a powerful tool for spreading Alexander's image and propaganda. By circulating coins with his likeness and related symbols across the empire, it says, Alexander reinforced his authority and promoted the unity of his territories under Hellenistic culture.
The post also says the coin's wide circulation helped standardize monetary systems in newly conquered regions and supported trade and the spread of cultural and political ideas across the Hellenistic world.
