Exactly 👌 the history of US dollar sign 💲 is interesting in this context, as its most likely origin has nothing to do with the American dollar and much more likely with the Spanish pesos. This one was widely known in the general population and there adoption (So no greater big brain logic, just giving the common man what he wants) Perplexity: The dollar sign ($) is used in the United States because, when the U.S. established its own currency after independence, it modeled the new dollar on the widely used Spanish dollar (or peso), which had been the most common currency in the American colonies for over a century. The Spanish dollar’s symbol and value system were already deeply familiar to Americans, merchants, and the broader economy.
