Trying to think about who would've been the #1 batsman and bowler in the game. Note that a lot of the time it would've been disputed:
The ICC rankings go back retrospectively to 1882. A previous version by Coopers & Lybrand started in 1877 when Tests began, so can fill in the early years. Top ranked batsman at the end of each calendar year since 1877 below. Years when no completed Test match occurred are excluded (1878, 1881, 1891, 1900, 1915-19, 1940-45).
12 – Sobers (1959-64, 1966-68, 1971-73)
11 – Hobbs (1910, 1912-14, 1920-22, 1924-27)
10 – Bradman (1931, 1933-39, 1946-47)
7 – Clem Hill (1902-04, 1906-09)

Among those never ranked first at year-end are Ranjitsinhji, Trumper, Macartney, Hammond, Headley, Worrell, Weekes, Graeme Pollock, Barry Richards (not enough Tests), Greg Chappell, Martin Crowe, Kallis, Amla and Root.
Before Test cricket began in 1877, Grace was undisputed leading batsman for the nine years between 1868 and 1876. Adding these to his three years during the Test era would give him 12 in total.
