I have yet to see any series 2013 notes in circulation but I have seen them for sale on eBay...so they are out there. However, I have seen series 2009A $100 notes.
i've seen 2013 $2, $5, $10 and $20 online. any idea if there is a 2013 $50 note? also are the twos being released at all districts? i've only seen Minneapolis, San Francisco and Atlanta.
Based on this site...there have not been any 2013 $50 produced. http://www.uspapermoney.info/serials/
Seeing that you've got a coin as your avatar...you are aware that currency isn't dated like coins, yes? The series date on currency only changes when there's some change to the notes, like a new signature. So Series 2009 was in production until quite recently (and is *still* in production in a few denominations); it's just now being replaced by Series 2013. There are no notes dated 2010, 2011, or 2012. Series 2013 will then remain in production until the next signature change or design change comes along. So unless that happens, don't look for any notes dated 2014, either.... (I personally saw my first Series 2013 note over someone's shoulder on Sunday. Haven't received one in circulation myself yet.)
Thanks Clay...I wasn't aware that different denominations skipped letters, but overall they hit on every letter.
