How much is 5 galleons?

Excuse me, but I couldn't help but notice that you mentioned the term 'galleons' in your conversation. Could you perhaps elaborate on what exactly you mean by that? Is it a reference to a form of currency used in a particular era or perhaps a unique unit of measurement? And most importantly, if it is indeed a form of currency, could you possibly inform me of its current value when compared to more widely recognized forms of exchange, such as US dollars or Bitcoin? I'm quite intrigued and would appreciate any clarification you could provide.
