How much is 1fr in USD?

Could you please clarify for me, what exactly is 1fr? Is it a reference to a specific cryptocurrency, token, or perhaps a financial instrument that I'm not familiar with? And if so, could you elaborate on how I might be able to determine its value in USD? Is there a specific exchange rate that fluctuates, or is there a set conversion rate I should be aware of? I'm eager to understand the context behind this question and how I might go about finding the answer.
