The Weight Test: Using a Precision Scale

Compare unsleeved cards of the same printing and finish on a calibrated scale. Weight is supporting evidence, not a universal pass/fail threshold.

intermediatemedium reliability

What this checks

The mass of the card, which reflects the specific paper stock and coatings used by the official manufacturer.

Tools: Precision scale (0.01 g)

Real reference: genuine Sol Ring
Real reference: genuine Sol Ring (Limited Edition Alpha, 1993). Compare your card against a verified genuine scan like this — look for a weight consistent with comparable genuine copies, allowing for stock, finish, wear, and measurement variation. A counterfeit instead shows: different stock or added layers may cause a weight mismatch, but a counterfeit can also overlap the genuine reference range.

A weight consistent with comparable genuine copies, allowing for stock, finish, wear, and measurement variation.

Fake looks like

Different stock or added layers may cause a weight mismatch, but a counterfeit can also overlap the genuine reference range.

Step by step

  1. 1Calibrate the scale as instructed, zero it, and remove sleeves or holders.
  2. 2Weigh several genuine cards of the same set and finish to establish a comparison range.
  3. 3Weigh the suspect card under the same conditions.
  4. 4Compare against your reference range.
  5. 5Flag a card that sits well outside the range for further testing.

Why it matters

Objective and repeatable, but weight overlaps between genuine and good fakes, so it is a supporting test, not a verdict.
