Until the FIRST_CHANGE# is less than the ARCHIVE_CHANGE# in v $database. The value in ARCHIVE_CHANGE# is the SCN below which redo logs are forced to be archived.

And the ARCHIVE_CHANGE# in each indicates the earliest entry you'll see in V$LOG_HISTORY.

You'll need to create a new controlfile to change this, as this is controlled by the MAXLOGHISTORY parameter. An 'alter database backup controlfile to trace;' command will provide the currently set parameters in a script you can modify to increase or decrease the MAXLOGHISTORY value.
