How to Identify the Antiochos the Child Tetradrachm

Start with the obverse portrait. This tetradrachm shows a young head facing right, wearing the royal diadem and with curly hair. Focus on the youthfulness: the features are rounded and idealized rather than the heavier, more mature portraits found on later Seleucid silver. The diadem, a simple cloth band tied behind the head with ends trailing down the neck, is the standard mark of Hellenistic kingship and should be visible on a well-preserved coin.

Turn to the reverse and look for a martial figure carrying a spear and shield, shown either mounted on horseback or seated in a warrior stance. Around the type you should be able to find a Greek royal legend, usually including the title BASILEOS ("of the King") and a royal name, often accompanied by monograms or small control symbols. Reading even part of that legend helps confirm the attribution and separates the coin from similar Hellenistic reverses.

Check size, weight, and fabric together. A genuine tetradrachm is a large, thick silver disc, on the order of about 16 to 17 grams and roughly 28 to 32 mm wide, struck from hand-cut dies. Expect an irregular, slightly oval flan, uneven edges, and centering that can push part of the design or legend off the blank. The metal should look like high-grade silver, usually with grey age toning rather than a bright modern shine.

Beware of look-alikes and denomination confusion. Seleucid kings issued many tetradrachms with diademed profile heads, so it is the combination of a young portrait and a spear-and-shield martial reverse that points to this type rather than a mature-king issue or a seated-Apollo reverse. Smaller silver pieces (drachms and fractions) can share the imagery at reduced size and weight, so confirm the weight before calling a coin a tetradrachm.

Finally, watch for authenticity problems. Cast forgeries betray a seam around the edge, a soft or bubbly surface, and a dull, non-metallic tone; tooled or re-engraved coins show unnaturally sharp, scratchy detail added to worn areas or a legend that looks freshly recut. Because attractive examples are valuable, treat bargain-priced coins with caution and, for a significant purchase, rely on specialist attribution or third-party certification and, where available, documented provenance.

Frequently asked questions

How do I tell this from a tetradrachm of Antiochos IV Epiphanes?

Look at the age of the portrait. This coin shows a young, rounded, youthful head, whereas the mature Seleucid kings are usually rendered with heavier, older features. The reverse type and legend also help: match the martial spear-and-shield figure and read as much of the Greek inscription as possible.

What should the legend say?

Seleucid tetradrachms normally carry a Greek royal legend including the title BASILEOS ("of the King") and a royal name, placed around the reverse figure and often accompanied by monograms or small control marks that vary between dies and mints.

How can I confirm it is a full tetradrachm and not a smaller coin?

Weigh and measure it. A tetradrachm sits on the order of about 16 to 17 grams and roughly 28 to 32 mm across. Lighter, smaller coins with similar imagery are drachms or fractions, so weight is the key test between denominations.

What are the main warning signs of a fake?

A seam around the edge, a soft or bubbly surface, and a dull tone suggest a cast copy, while unnaturally sharp detail or a freshly recut legend on an otherwise worn coin suggests tooling. For valuable examples, seek specialist attribution or certification.
