How much is 1 shilling?

Excuse me, could you please clarify for me the current value of one shilling? I understand that shilling values can vary greatly depending on the country and currency system in question, so I'm curious to know the specific amount in terms of a widely recognized currency, such as the US dollar or the euro. Is there a fixed exchange rate for shillings, or does it fluctuate over time? I'd appreciate any information you can provide to help me understand the worth of one shilling in today's market.
