Every Series. Every Signature. In Your Pocket.

Leave the books at home. Be ready with a reference catalog whenever you see an interesting note.

Every collector knows the moment. You're at a table at a regional show, a dealer slides a small-size $10 across the case, and something about it isn't quite what the flip says. The seal looks right. The series says 1934A. But is that the North Africa note, or the ordinary blue seal that someone has described generously? Your Friedberg is on a shelf three hundred miles away.

This is the job the NUMA catalog was built for. Open it, go to Silver Certificates, ten dollars, Series 1934, and the whole family is there: 1934 (Julian–Morgenthau), 1934A, 1934B, 1934C, 1934D, each with its Friedberg number, its signature combination, its seal, and — the part that matters at the table — the variants. The yellow-seal North Africa emergency issue sits beside its blue-seal cousin with the differences spelled out. Star notes have their own line. Mules, where the catalog knows them, are noted.

We built the catalog the way a collector reads a catalog: by type, then denomination, then series, then variety, with the same numbering you already use. It doesn't reinvent the references; it carries them. Large size or small, Fractional Currency to the current Federal Reserve Notes, Legal Tender, Gold Certificates, National Bank Notes by charter — the structure is the one on your shelf, and the entries are the ones you'd look up.

The deep dive is where it earns its keep. Tap a series and you get the signature combinations for every district or block that applies. Tap a variety and you get what distinguishes it from the one next to it, so “is this the scarce one?” becomes a thirty-second check rather than a phone call to a friend. When you're comparing two notes in two flips, having the reference open beside them is the difference between a confident buy and a polite “let me think about it.”

And when you're home again, the same catalog is on your computer at ngtnuma.com, at a size you can actually read, for the evening when you want to work through an entire series with a cup of coffee and no dealer waiting.

The catalog is currently free to use. It's a reference. Use it like one.
