I've wanted to put together a sort of type set of small note $10 bills of the various types. A quick look through guide book identified the following types - The Fr.1700 note is a bit beyond my budget, as I tend to focus on coins over bills, so I'll almost certainly skip it. And the green seal Federal Reserve Notes aren't as fascinating to me (though the four series are distinct and noticeably different) as the eight key types I'm trying to collect. Here are the four I've collected thus far. Fr.2400 graded, the rest are raw. I'm hoping to add Fr.2303 and Fr.2309 later this year.
