Only dead white men, you say? Well what about the Sacagawea dollar, the Susan B. Anthony dollar, the Indian Head nickel and the Indian Head cent?
Wow, I never realized until right now that 75% of non-dead white men coins have Native Americans on them. That's kind of spooky.
Hey, the Sacagawea dollar's in circulation! Last year they made 24,640,000 of them!
And look at this, from wikipedia: Although not widespread in the United States, the Sacagawea dollar is very popular in Ecuador and other foreign countries that have made the US dollar their currency. Since dollarization, an estimated 500 million coins, approximately half of those minted, have been used in Ecuador, El Salvador, and other Latin American countries.
