How many hero coins are there?

Could you please elaborate on the specific context surrounding the term "hero coins"? Are you referring to a specific cryptocurrency or token that is tied to some form of hero-themed game, collectible, or platform? Without a clear understanding of the definition and context of "hero coins," it's difficult to accurately answer the question of how many exist. Could you provide more details about the nature and purpose of these coins? Additionally, if they are a digital asset, are they traded on a cryptocurrency exchange, and if so, which one? This information would help me provide a more precise response to your query.
