It couldn't have been in 2008 because Bitcoin's genesis block was mined on January 3rd 2009 (in other words, the BTC blockchain didn't exist yet).
The only 2009 exchange that I'm aware of is the New Liberty Standard, which set exchange rates based on the cost of electricity, but this
no longer exists.
If your friend does not have access to a wallet containing his private keys (most likely a wallet.dat file in an old Bitcoin QT wallet), he most likely will never have access to these coins.
