the most errors in a game is 12 - there have been a number of games with 11 and 12 errors by a team - but they all have been before 1905 - when fielders gloves were very small, and official scoring was probably much different.
They consider anything after 1900 to be the "modern era".. but I would guess when it comes to fielding, you would have to look at games 1970 and later to be comparable due to scoring changes, glove size changes, etc....
Wonder what the "record" is for errors by 1 team in a game from 1970 on? I doubt this is something that would be easily searchable...
