U.S. Mint issues commemorative coins celebrating Harriet Tubman. Here's what they look like.

Starting Thursday, admirers of Harriet Tubman and numismatists alike can buy coins commemorating the famed abolitionist and human rights activist issued by the U.S. Mint.

The agency is offering a $5 gold coin, a $1 silver dollar and a clad half-dollar, featuring designs depicting three different eras in Tubman's life, including her historic role transporting enslaved people to freedom through the Underground Railroad. The coins can be purchased individually or as part of a set.

"We hope this program will honor the life and legacy of Harriet Tubman and inspire others to learn more about this amazing woman," Ventris C. Gibson, director of the U.S. Mint, said in statement.
