Yes -- they started grading in '73.

Some of the old-time mares won a lot of very important races.

Gallorette won the Met Mile, won the Brooklyn Handicap, Carter Handicap, and Whitney. Those are four of the five major handicaps in New York.

Esposa, the champion mare of 1937 and 1938 won about 10 major stakes on dirt against males.

Regret won her career debut in the Saratoga Special. Won 2nd time out in the Sanford. Won 3rd time out in the Hopeful. Won 4th time out in the Kentucky Derby off of a 9 month layoff. Won 5th time out in the Saranac. Five would be Graded Stakes wins against males in the first 5 starts of her career.

In her only two lifetime starts against females, Regret won an ALW race by 8 lengths going 5.5 furlongs for her five-year-old debut. And she won the Gazelle by 3 lengths under 129lbs.
