How much is 1 crown in today's money?

Could you please provide some context on what kind of crown you are referring to? There are various currencies and systems that have used the term "crown" throughout history, such as the British crown coin or the Danish krone. Without knowing the specific context, it's difficult to give an accurate conversion to today's money. However, I can ask you: Are you looking for the current exchange rate of a specific currency that was previously known as a crown? Or are you inquiring about the historical value of a crown from a particular era? Knowing this information will help me provide a more precise answer to your question.
