A single price for a preferred security I hold has been downloaded since 7/5 with the decimal point in the wrong place.... actually missing. Sure made me feel rich for a few seconds, but I figured out where it was coming from and edited it in the price history to the correct value.
What I'd like to know is how this happens? Who supplies the price histories, Quicken from some special source or the brokerage I have the security held in?

Potentially, both Quicken and the brokerage are legitimate sources for security prices. Quicken can not download prices for all securities (bonds, for example); while your financial institution should download prices for every security you hold there.
There are probably a couple of ways you could get a better handle on the source of your incorrect price. Perhaps the simplest would be to create a New (test) Quicken file, add the problem security to the Watch List, and see what price downloads.
[You can also check the OFXlog for your regular file; it will have the holdings downloaded by your brokerage, which will contain prices for each security you hold there.]
