I've started up a small collection of paper bills, but I'm wondering if I should keep them or spend them? Some of you guys with a bigger collection might think mine is lame, but here it is:
Series 1995 $1, Serial number C0007?A
Series 2003A $1, still in pretty good condition for its age
Series 2009 $1 (I know what you're thinking, but it's in CU condition and remember, series 2009 is no longer being printed)
Series 1969B $1, in pretty decent condition for its age.
Series 1995 $5 (pretty beat up but not ripped and will probably be replaced if I ever come across an upgrade, but I rarely see small face bills anymore)
And finally, I have a $5, $10, and $20 from series 1999, since bills were redesigned, but non colorized when I first started learning about money.
Any opinions?
