Nancy Sinatra – 82 – $50 Million

In the music industry, Sinatra is undoubtedly one of the most recognized surnames in the business. Apart from the ever-iconic Frank Sinatra, the late singer’s daughter, Nancy, is also a highly regarded star. Throughout her childhood, she was already well accustomed to music and learned how to play the piano. She also took lessons in dancing and acting.

Starting her career around the late 1950s, Sinatra got her first big shot to fame in 1966 thanks to her number-one hit record, These Boots Are Made for Walkin’. Other notable tunes she released through the years include Sugar Town, the Bond theme song You Only Live Twice, and a duet with her father titled Somethin’ Stupid. While she hasn’t released any new songs just yet, the singer recently spent a portion of investment money starting an online shop called Nancy’s Boutique, where she sells signed items, CDs, and other merchandise.
