* The TM is a Trademark: The TM symbol represents a registered trademark, which is a legal protection for the Pokémon brand and its associated artwork. It's a key way to differentiate genuine Pokémon cards from counterfeit ones.
* Counterfeits Often Lack the TM: Counterfeit Pokémon cards often lack the TM symbol because they're designed to mimic the real cards without infringing on the copyright.
* Genuine Cards Always Have It: Every legitimate Pokémon card produced by The Pokémon Company has the TM symbol on the back.
So, if a card doesn't have the TM, it's almost certainly fake.
However, there are some exceptions:
* Older Cards: Very early Pokémon cards from the first few sets might have a different trademark symbol (like "© 1995 Nintendo" or "© 1995 Wizards of the Coast") instead of the standard TM. These are still considered genuine.
* Promotional Cards: Some promotional cards might have unique designs or branding and might not have the standard TM symbol. However, they will still have some form of official branding or trademark.
If you're unsure about a card's authenticity, it's always best to consult a reputable source or expert for confirmation.
