Both sides are the same whereas normally one side has the 4Q logo and the other has either 666 or 999. According to TCR it doesn't say which side is on the error chip but it says it wasa fro the year 2000 chip so I guess it would either be the 4Q logo on both sides or 999 on both sides. If you have one like that I would happily buy it from you.
