Apple’s unadjusted stock price on 7/1/2006 was about $67.96 per share at the monthly price history level, with July 2006 listed at that unadjusted price for Apple.

If you want the exact daily closing price for that specific date, I’d need a historical daily feed that can be queried directly, but the July 2006 unadjusted reference point is $67.96.
