“Endless Love” by Diana Ross and Lionel Richie was certified Platinum by the RIAA. The hit was her 18th number one single and the biggest selling record of her career, including her records with The Supremes. Her biggest hit, “Endless Love,” is not a big collectible at no more than $5.00. However, her first big hit with the Supremes, “Where Did Our Love Go,” can now sell for a $100.00 with its picture sleeve.
