Swayze's widow Lisa Niemi is auctioning off a bunch of his memorabilia in Los Angeles on April 28th and 29th.  The items include the jacket and the surfboard, which are worth $4,000 to $6,000 each.  

Then there's the maroon silk shirt he wore in "Ghost" which has an estimated value between $2,000 and $4,000.

And the wetsuit he wore in "Point Break" is going for the same price. 

Lisa says she's excited to share Patrick's "incredible life" with his fans.  And she's donating part of the money to the Pancreatic Action Cancer Network.  Patrick died of pancreatic cancer in 2009.  He was only 57.
