Counterfeit Detection

The Zuid‑Afrikaansche Republiek (ZAR) coinage is among the most frequently counterfeited world series. This guide synthesises foundational research (Levine 1974) with modern authentication methodology (NGC) to help collectors identify forgeries.

Critical Principle

Repeating DepressionsIf two coins show identical marks, they are almost certainly fake.
Weight AloneGold fakes can be within tolerance.
Mushy DetailsTransfer die manufacture.
Cast PorosityTiny pits from casting.

100 copies were issued in a deluxe limited edition, signed by the author. Features a foreword by Mrs F.B. Lang, President Burgers' granddaughter.

Availability: Out of print – appears occasionally through antiquarian booksellers.

Levine's methodology – comparing genuine vs counterfeit specimens – established the foundation for modern authentication.

The Repeating Depression Principle

"It is virtually impossible for two genuine coins to have marks in the exact same locations, so if two coins show identical abrasions there is a very good chance that they are fake." – NGC

Counterfeiters make a die using a genuine example. The details of that specific coin – including all its marks and imperfections – are transferred onto the die. Every counterfeit struck from that die will show the exact same marks in the exact same locations.

1895 Gold ½ Pond – Documented Locations

Obverse

  • Kruger's mouth
  • Kruger's ear and into hair
  • Bottom of his coat

Reverse

  • The "8" of the date
  • Ribbon above the first "A" of "MAAKT"

These fakes are gold and within weight tolerance – only visual examination reveals the truth.

1893 Silver 2½ Shillings

Location 1

Long depression below the flower – identical on multiple examples.

Location 2

Three prominent marks in the banner – precisely positioned identically.

These two coins, submitted separately, showed identical depressions. Statistically impossible for genuine coins – both struck from the same counterfeit die.

Cast Fakes

Produced by pouring molten metal into molds. Distinct characteristics:

CharacteristicDescriptionDetection
PorosityTiny air bubbles from castingMagnification reveals small pits
"Orange peel" textureUneven surface from moldVisible under angled light
Soft detailsLoss of sharpnessCompare to genuine
Casting seamVisible line where mold halves metEdge examination
Weight issuesAir bubbles create voidsPrecision scale

Levine's work extensively documents cast forgeries of ZAR coinage, including contemporary fakes from the 1890s.

Transfer Die Fakes – The Modern Threat

Unlike cast fakes, these are struck – not cast – and can closely resemble genuine coins in weight, diameter, and even metal composition.

Manufacturing Process

  1. Select a genuine coin (the "host")
  2. Create an impression die from the host – every surface detail transfers
  3. Heat treat the die to harden
  4. Strike blanks with counterfeit die

Known Transfer Die Fakes in ZAR Series

  • 1895 ½ Pond – NGC documented
  • 1893 2½ Shillings – NGC documented
  • Various Ponds – Levine comprehensively documented

Authentication Protocol for Collectors

Step 1: Visual Inspection (No Magnification)

  • Overall appearance – natural wear pattern?
  • Color – appropriate for metal?
  • Edge – consistent, visible seam?
  • Rims – even, appropriate thickness?

Step 2: Low Magnification (5×–10×)

  • Surface texture – natural flow lines vs. casting porosity
  • High points – even wear vs. mushy details
  • Lettering – sharp and consistent vs. soft, uneven
  • Date – proper style, no alteration evidence

Step 3: High Magnification (20×+)

  • Die markers – known genuine vs. known counterfeit depressions
  • Surface marks – random and unique vs. identical (if comparing multiple)
  • Reeding – sharp and consistent vs. blurry, wrong pattern

Step 4: Physical Measurements

  • Weight – precision scale (note: gold fakes can be correct)
  • Diameter – calipers
  • Thickness – calipers

Step 5: Comparison

  • Compare to known genuine specimens
  • Compare multiple suspect coins – identical marks?
  • Compare to documented fakes – known depression locations

Step 6: Professional Certification

  • NGC – largest ZAR population, maintains counterfeit database
  • PCGS – strong market acceptance
  • SANGS – local expertise

"If you ever have reason to question the authenticity of an uncertified coin, it is recommended that you submit the coin to a reputable third-party coin grading company for certification." – NGC

Common Pitfalls and Warnings

The "Weight Tolerance" Trap

Gold counterfeits can be within weight tolerance – demonstrated by 1895 half‑pond fakes. Weight alone is insufficient.

The "Looks Old" Fallacy

Counterfeiters can artificially age coins. Wear patterns can be faked. Age is not authenticity.

The "One Coin" Limitation

Without a second suspect coin, the repeating depression test cannot be performed. Maintain reference images of documented fakes.

Over‑Reliance on Single Diagnostic

Use multiple diagnostic points. A genuine OS initial on a double‑shaft coin is correct; the same initial on a single‑shaft coin is impossible.
