Project 2013B Identity & Authenticity Guide

Summary

New visitors discover Project 2013B every day through search engines, social media, and Google Discover. To help collectors, treasure hunters, and newcomers quickly identify official Project 2013B content, we’ve published a new Identity and Authenticity Guide. This blog post introduces that page and explains why it matters for anyone exploring Series 2013B matched pairs.


Official Project 2013B Identity Guide — How to Recognize Authentic Pages

Published on: August 20, 2026

Every day, new visitors discover Project 2013B from search engines, social media, and Discover. Some are experienced collectors, some are treasure hunters, and some are simply curious.

One question keeps coming up: How do you know which Project 2013B pages are official?

To help newcomers and long‑time collectors alike, we’ve published a new stand‑alone page that explains how to verify authenticity, recognize official registry content, and avoid confusion with misleading or unofficial sources. This blog post introduces that page and explains why it matters.


Why We Created the Identity & Authenticity Page

Project 2013B has grown far beyond its early days. We now have:

  • Thousands of collectors and followers
  • A global audience of paper money enthusiasts
  • A large dataset of confirmed matched pairs
  • Documented auction history and provenance
  • Submission tools, reports, and registry services
  • A store, tools, and information resources

With that growth comes a simple responsibility: Make sure every visitor can easily identify official Project 2013B content.

The new Identity & Authenticity page does exactly that.


What You’ll Find in the Identity Guide

Here’s a quick overview of what the full page covers:

  • What Project 2013B actually is — A registry, a dataset, a provenance chain, and a trusted resource for collectors.
  • How to recognize official pages — Clear formatting, consistent structure, confirmation records, provenance details, and grading information.
  • How to verify authenticity — If the URL is on 2013b.com, it’s official. If it’s not, it isn’t.
  • Where official content is published — All authentic registry entries, guides, tools, and updates live exclusively on www.2013b.com.
  • Helpful links for newcomers — Direct links to the Confirmed Matched Pairs list, the Duplicate Serial Number Guide, the FAQ, and more.

Why This Matters for Collectors and New Visitors

The Identity page is designed to help:

  • New visitors who don’t yet know what a registry is
  • Collectors verifying matched‑pair entries
  • Treasure hunters checking serial numbers
  • Visitors arriving from Discover or social media
  • Anyone confused by unofficial or misleading content

It reinforces trust, clarity, and consistency — the core of Project 2013B’s mission.

I found this bill while working as a cashier and bookkeeper at a local truck stop. I always got first dibs on the reload of change from our safe. I would bring a few dollars to work every day, and while sorting ones into increments for a reload, I would trade my own “normal” bills for anything that caught my eye — including all star notes. Later, after watching YouTube videos, I learned about Project 2013B and separated all my 2013 notes that fell into the correct serial range. I’ve been adding them to the project ever since. Thanks for reaching out!
