There isn’t a credible public source that gives a definitive count of how many 1958 Topps Roberto Clemente yellow cards are counterfeit. What the available hobby references do show is that the card is commonly discussed and that suspicious or reprinted examples circulate, but they do not publish a verified tally of counterfeits.

What can be said confidently

  • The card in question is the 1958 Topps Roberto Clemente, often listed as the yellow-background #52 variation.
  • Hobby discussions and marketplace listings show that fake, reprint, or altered examples do appear, but those sources are anecdotal rather than statistical.
  • Because counterfeits are not centrally reported across the market, there is no authoritative “how many” figure from the sources reviewed.

Practical takeaway

If your goal is buying or authenticating one, the safer approach is to judge the specific card, not the market as a whole:

  1. Check paper stock, color, and aging consistency.
  2. Compare the print dots, borders, and registration to verified examples.
  3. Prefer graded examples from major third-party graders.
  4. Treat unusually bright color, overly clean corners, or artificial aging as warning signs.

Bottom line

The honest answer is: no verified number is publicly available. The card is known to be counterfeited often enough that caution is warranted, but the hobby sources I found do not support a precise count.
