By 1899 W.G. Grace, then 50, was no longer Gloucestershire's automatic first choice. A row over his Test selection (he was dropped after the 1899 Trent Bridge Test) and his deteriorating relationship with the Gloucestershire committee combined with an attractive offer from the Crystal Palace Company. Grace was guaranteed £600 a year and a share of the gate — large money for the era — to set up and run a first-class cricket club at the company's Sydenham ground.
London County CC played first-class matches from April 1900 to 1904. Grace assembled a side of past internationals (Billy Murdoch, Walter Read, Stanley Crowther) and promising amateurs, and the club's matches were given first-class status by the MCC despite not being part of the County Championship. The first match was a heavy defeat by Surrey at The Oval; the first home match three weeks later, against the same opposition, was drawn.
The public never warmed to what were effectively friendlies. With no championship status, the matches lacked competitive bite. Grace himself made plenty of runs (his 1903 season for London County included a hundred at age 55) but the club lost first-class status in 1905. It continued in club cricket until 1908, when the Crystal Palace Company ran out of money and the ground was closed. Coincidentally, 1908 was also the year of Grace's last first-class match, for the Gentlemen of England against Surrey at The Oval, in which he scored 15 and 25.
