    Are you sure about that? The whole "wallet recovery words" system did not exist in 2009. – Raghav Sood Jan 31 at 4:05

    Moreover, no version of Bitcoin Core has ever had a recovery phase. The earliest was 2011 with Blockchain.info. – Anonymous Jan 31 at 4:06

I believe the only possible answer for this time (assuming you mean 2009, no wallets existed before then with recovery mnemonics) is that the wallet was blockchain.info. Different to now, at the time it used a "recovery mnemonic", which was an encoding of your password rather than the keys in your wallet. Unfortunately if this is the case you need to also know either the 'wallet identifier' (looks like fbb4b1dd-1b30-4cc2-b745-b586e4f3cb57), or the original wallet.json.aes file.

    According to Wikipedia, blockchain.info didn't start until 2011. Bitcoin itself only started in January 2009, so if the dates are right, GPHM was an extremely early adopter. – Nate Eldredge Jan 31 at 7:20
  • Yes. I assume they misremember. – Anonymous Jan 31 at 7:46
