Hello:

I'm new to all of this numismatic collecting.

I have a $5 dollar bill that has a serial number that starts with MF.
Can someone let me know what that means?

Thanks so much, this site is awesome!

B = New York
C = Philadelphia
D = Cleveland
E = Richmond
F = Atlanta
G = Chicago

With the little info provided I'm going to say it is a Series 2013.

On Uspapermoney.info it states that all serial numbers in this series begins with M. http://www.uspapermoney.info/serials/f2013_q.html

Yup, for all bills $5 and up, the first letter designates the series of the bill. This extra letter was added first to the 1996 redesign, so any bills 1995 and older only have 1 leading letter.
A- 1996
B- 1999
C- 2001
D- 2003
E- 2004
F- 2003A
G- 2004A
H- 2006 (uncolored)
I- 2006 (colored)
J- 2009
K- 2006A
L- 2009A
M- 2013
And as hajduk said, the second letter indicates the Federal Reserve Bank it was produced for.

That's some darn cool info. Hmmm... unless I'm wrong, and I'm never wrong (thank you, Prince Humperdink), we're exactly half way through the alphabet.

Wonder what they're going to do after Z in another 20 or so years? AA, AB, AC?

Coincidentally, that also happens to be what it says on my wallet.

Don't forget when they change series(about every 3 years), they can re-use letter combinations. Plus with each prefix combination(MF, NF, OF, etc.) there are a possible 26 suffix letters they can use. With 26 x 99,999,999 notes per prefix combination(MF-A, MF-B, etc), I don't think they have to worry.

But remember they restart the block (suffix) letters at A for every series change.
JF-A was followed by JF-B and so forth, but as soon as series 2013 rolled around they restarted the block letter at MF-A. Also O and Z are skipped for block letters. We'll see if they skip O as a prefix, but that should be coming in less than 10 years.
We'll probably hit the end of the alphabet in about 20-30 more years, so it'll definitely be interesting to see what they do. My guess is just restart at A.
