I Found An 1849 5 Dollar Coin From Pacific Company California. It Has An Eagle On The Back And What Appears To Be Sun Like Rays On The Front. Can Anyone Tell Me About It?

It's a night cap on the front

I have one too.  I'm very curious what you find out.  I know it's called the liberty cap.  Check this site out.  It's for the $10 version, but I found it interesting.  americanhistory.si.edu/collections/object.cfm?key=35&obj
