Lion, King, and Coin
Nam, Jeong-hee. Lion, King, and Coin. Illustrated by Lucia Sforza. Grand Rapids: Eerdmans Books for Young Readers, 2017.
This is an informative children's book about how we came to have money. It discusses bartering, exchanging goods, and the difficulty of finding someone who actually wanted what you had to trade before currency. It talks about some of the precursors to coinage. The illustrations seem to fit the period of history being discussed.
