Here is some other info I discovered here:
http://coins.about.com/b/2007/04/03/washington-dollar-update.htm (scroll down)
The CWI# on the boxes of Washington Dollars have, without exception, been CWI#103 for Philadelphia mint coins, and CWI#102 for Denver mint coins. CWI stands for Coin Wrap, Inc., which is a contractor for the government. Three different Coin Wrap employees have told me that the CWI number is a facility, or location number. However, Coin Wrap itself won't confirm or deny anything about these numbers, saying only that they are for internal use only, and are meaningless to the public. There has been some speculation that the CWI# might be a customer number, and that the coins are being wrapped at multiple locations for the two main customers (the Denver and Philly mints,) but I stand by my information for now. If someone who works for Coin Wrap wants to correct my information in a verifiable manner, I'm all ears.
