Oprah Winfrey has raised more than $600,000 for charity with a yard sale — and, as the Los Angeles Times reported, she still has 250 lots up for sale.

One of the top items from her home was a set of six embroidered 18th-century armchairs that went for $60,000, nearly 10 percent of the money raised so far. A combination of in-person bids at the Santa Barbara Polo & Racquet Club and online bids boosted some items to more than 10 times their estimated value.

All proceeds from the yard sale will go to Winfrey’s girls leadership academy in South Africa.
