I definitely prefer hunting for nickels. There's always something to find, whether it be pre-49's, War Nickels, Buffalos, the occasional V nickel, or my favorite - foreign coins. I have only been searching since the start of this new year, but I'm three coins away from pulling a complete Jefferson set out of circulation. I expect that once I complete it I may start all over again.
I also enjoy searching halves, but that's just for the silver.
