Hey, that sounds like a math problem! :D Let's see here...there are 254 different possible serial numbers that contain only the digits 5 and 6....
The late sixties was when the Federal Reserve finally ran low on $500's and $1000's, which hadn't been printed since the last 1934-series...
For anyone who might be considering a project like this, I'd just like to point out that I've got charts posted on my website listing what block...
If the schedule hasn't slipped, then production of Kodachrome $100's should begin long before Bush leaves office, so they'd have the...
They've announced that one new feature of the Kodachrome $100 will be an embedded thread with a holographic image on it that appears to *move*...
The "necessary know-how" part. I don't have a clue how to do all the scripty-php-java-whatsit that would be needed on the back end. (Notice that...
No...not that I'm entirely sure I'd notice if I had. I remember once running across someone who had a standing offer of like $100 for a note with...
The problem is that it looks for all sorts of kinds of mathematical uniqueness, some of which collectors don't typically care about (like whether...
If that's the kind of information you're looking for, then: The ultimate book in this direction is Chuck O'Donnell's Standard Handbook of Modern...
I'm confused by your "10 to the 5th" references. That'd be 100,000, which number I don't think I used anywhere.... To count the number of...
This is actually even easier--with radars there's no restriction that the digits have to be different, so you don't get factorials, just powers of...
Almost, but not quite. The standard print runs for star notes at the time were 20,000 sheets, or 640,000 notes. So Spock's note is from the tail...
Easy: the first half of the digits can be anything at all, and the second half then have to be an exact match (in reverse). So just count the...
The letters start over with each new series, so it's not often that a series runs long enough to get all the way up to X. The most recent times...
Also note the mismatched typefaces of the 'A' suffixes in the two serial numbers of the $20. The higher-crossbar 'A' that appears in the...
Everything was printed at the BEP in Washington. The notes were then issued to the banks in the form of six-note sheets. If you go back to the...
The second note in the picture is a bit special...it's a 1935G with motto star. The motto "In God We Trust" was added to the back of the $1 bill...
It's not a question of *when*; it depends on what type of currency you're looking at. When star notes were first introduced in 1910, the star...
That edition must've been published while the 2003 series was still in production, then.... The total printage for the San Francisco stars ended...
:confused: Huh? The Comprehensive Catalog (Hessler/Chambliss) says it's the USS New York....
