Chimera Gaming recently came across a Black Lotus with a genuine Collector's Edition front, but a swapped back. The card had been altered, priced correctly once identified, and has since been bought and sold with everything disclosed. Here's what we found and how we found it, so you can spot the same thing.

Three checks, from easiest to most reliable.

1. 1

   Corners

   Factory-rounded corners are smooth and consistent. Trimmed corners, from a CE card cut down to imitate a rounded original, often look slightly uneven up close. Watch for resellers passing off trimmed corners as ordinary wear or damage.

2. 2

   Weight

   Weigh the card on a precision scale with 0.01g accuracy. A genuine card sits at 1.7 to 1.8g. Anything over 1.8g gets flagged as suspicious on the spot, since a re-backed card has two glued layers and typically runs heavier, often 1.9g or more. That's enough on its own for us to take a harder look with the other checks below.

3. 3

   Mana Symbol Alignment (Expert Level)

   The "0" mana symbol on Black Lotus sits in a slightly different position depending on the printing. Since re-backing only touches the back of the card, this front-plate detail still identifies the original printing regardless of what back has been glued on.

   • Alpha: misaligned downward
   • Beta: misaligned up and slightly right
   • Unlimited: misaligned up
   • Collector's Edition: well centered, yellow layer misaligned slightly left

   This is the most reliable check because it can't be faked by swapping the back. A close-up comparison of mana symbol placement across printings is shown below.
