Just curious what people think about sequential bills -- Are sequential bills worth keeping (mostly for investment purposes)? Do sequential bills command any sort of premium after a number of years? In my mind, I feel like there are better investments than stashing currency away, but then, why do people stash stacks of money away? All of this said, I'm mainly a coin collector, but my bank had new bills that they disbursed with my withdrawal, which got me wondering about sequential new bills.. Thoughts?
