How much is a step card?

Excuse me, could you please clarify what you mean by a "step card"? Are you referring to a type of cryptocurrency, a loyalty card, or perhaps something else entirely? In general, the value of any card or cryptocurrency can vary greatly depending on factors such as market demand, scarcity, and the underlying technology or services it represents. If you could provide more context or specifics about the "step card" you're asking about, I might be able to give you a more accurate estimate of its worth.
