How much is 1 islm to USD?

I'm curious, could you please clarify what you mean by "1 islm"? I'm not familiar with a cryptocurrency or token named "islm". If you're referring to a specific digital asset or token, it's possible that it's not widely known or traded on major exchanges. In general, the value of a cryptocurrency or token in USD can vary greatly depending on the market conditions and the demand for that particular asset. To find out the current value of a specific cryptocurrency or token, I recommend checking reputable cryptocurrency exchanges or market data websites.
