Early career

Coin played at Clemson University, where she was an All-American, All-ACC, and ACC Player of the Year.^[7] She also holds numerous Clemson Women's Tennis records.^[7] Coin graduated from Clemson with a degree in mathematics.^[8]

2008

Coin and her doubles partner Violette Huck made it to the second round of the French Open women's doubles draw.^[1] Coin's breakthrough came at the US Open when she was ranked 188th in the world.^[5] She entered the main draw as a qualifier after defeating Amanda McDowell, Sesil Karatantcheva, and Elena Baltacha in the qualification rounds.^[9] This was the first time she had entered the main draw in singles at a WTA tournament.^[10] In the first round, she defeated Australian Casey Dellacqua 7–6, 7–6.^[9] Coin then rose to prominence and made worldwide headlines when she defeated world No. 1 and top-seeded Ana Ivanovic in the second round^[3][4][5] 6–3, 4–6, 6–3. ESPN^[3] and Sports Illustrated^[5] both called the win one of the greatest upsets in tennis history. Unfortunately, her parents only got to watch highlights of the match since Amélie Mauresmo, who was playing at the same time, was the one shown on French television.

Prior to Coin's upset victory, it had been 41 years since the top-seed had lost so early at the US Open,^[3][4][5] the previous time being when Maria Bueno lost in the second round of the 1967 U.S. National Championships.^[4] At the time of her victory against Ivanovic, Coin was ranked world No. 188.^[11]

She then lost 4–6, 4–6 to compatriot Amélie Mauresmo in the third round.

2009

Coin took on Mauresmo in the second round of woman's singles at Brisbane. The women played for approximately 3 hours, with Mauresmo eventually winning 5–7, 6–2, 7–6, after Coin held match points.

Coin beat Elena Vesnina 6–4, 4–6, 6–1 in the first round at the Australian Open. She fought hard, but ultimately fell to No. 14 Dominika Cibulková in three sets at Wimbledon.

2010

In the first round of the Australian Open, Coin recovered from a set down to defeat local favorite Alicia Molik 3–6, 7–6, 6–3 before losing in straight sets to Francesca Schiavone 3–6, 4–6.

2015

Partnering Emily Webley-Smith, Coin won the $100,000 tournament in February at Midland, defeating Jacqueline Cako and Sachia Vickery in the final. In November, she announced that the 2015 Open de Limoges will be her last professional tournament.
