Click load raw data
This raw data only maintains daily prices. This is probably the closing price for the day, but I can't be sure of that.
I'm not sure how bitcoin charts actually collects this information from the other providers. I hope other

If you're looking for a one-stop shop for lots of different exchanges/markets, Coinigy provides historical crypto data. It's not free but probably one of the better sources.

2Thats a good starting point, but I don't know how "authoritative" it is since it seems to be a 3rd party. I wonder how they collect the information in the first place. Do you know if they simply screen-scrape the info? – goodguys_activate – 2012-09-23T19:56:10.720

@makerofthings7, BitcoinCharts is the main markets watch website, operator Nils Schneider aka tcatm - Bitcoin developer, owner of BitcoinWatch, creator and owner of BitcoinCharts, GPU mining software and JS web interface - https://en.bitcoin.it/wiki/People . It as authoritative as it gets in Bitcoin community. Every exchange listed on this site upload its historical data on the website - http://bitcoincharts.com/about/exchanges/
