Currency Web Site

[Dozer D]

I have an opportunity to view a large stack of various denom bills. Was wondering if there is a good web site for listings, what bills to watch for ( red seals, blue seals ), years to watch for etc.
Only because I may be able to buy these bills at FV.
Your comments will be appreciated, thanks, DozerD
