Nickel Coin Mares' Standard Open NH Flat Race

The Nickel Coin Mares' Standard Open NH Flat Race is a Grade 2 National Hunt flat race in Great Britain which is open to fillies and mares aged four to six years. It is run at Aintree over a distance of about 2 miles and 1 furlong (3,420 metres), and it is scheduled to take place each year during the Grand National meeting in early April.

The race is named after Nickel Coin, the winner of the 1951 Grand National and the most recent mare to win the Grand National. It was promoted to Grade 2 status in 2016 having previously been run as a Listed race.
