Pick Number
Pick Number (P-#) is a standardized catalog reference used to identify and classify banknotes within the Standard Catalog of World Paper Money (SCWPM).
It is the most widely recognized global identification system, enabling precise reference to banknotes across countries, languages, and markets.
How It Appears
A Pick Number is assigned to a specific banknote type within a country’s catalog listing and is written using the prefix “P-” followed by a number (e.g., P-45).
This number represents a distinct design type rather than an individual note. Variations within the same type—such as changes in signatures, dates, or minor design elements—are indicated using lowercase suffixes (e.g., P-45a, P-45b).
A key distinction for collectors lies in suffix hierarchy. Lowercase letters typically denote minor varieties within the same design type, while uppercase prefixes or suffixes may indicate fundamentally different categories, such as Specimen notes (S), Replacement issues (R), or other specialized designations depending on the catalog structure.
Recognizing these distinctions is essential, as a small letter change can represent a significantly different and often rarer classification within the same visual type.
Pick Numbers appear in auction listings, dealer inventories, grading labels (PMG, PCGS), and collector databases, forming a shared identification language across the market.
Functional Role
The Pick Number system functions as a universal classification framework that standardizes how banknotes are identified and referenced globally.
Named after Albert Pick, the German numismatist who developed the system, it transformed banknote collecting by introducing a consistent, cross-border numerical language. A specific Pick Number refers to the same banknote type regardless of country, language, or marketplace.
This system enables precise communication between collectors, dealers, grading companies, and auction houses—eliminating ambiguity and reducing reliance on visual comparison alone.
At the same time, Pick Numbers reflect catalog editorial decisions. As research evolves, classifications may be refined, expanded, or reorganized, meaning the system is authoritative but not static.
Why It Matters to Collectors
For collectors, the Pick Number is the structural backbone of organized collecting.
It allows precise identification beyond denomination or country, making it possible to distinguish between visually similar banknotes that differ in signatures, issue types, or subtle design variations.
Pick Numbers are essential for building structured collections, tracking missing entries, and navigating the global market with clarity. When a note is referenced by its Pick Number, it establishes an exact and universally understood identity.
For advanced collectors, however, the Pick system is a foundation—not an endpoint. Some meaningful variations, such as subtle paper differences, minor plate changes, or print nuances, may exist without separate catalog recognition.
In these cases, value emerges beyond the catalog, requiring direct observation and specialist knowledge.
Pick Number vs TBB Number
The Pick Number system remains the legacy global standard, widely used in auctions, dealer listings, and grading systems such as PMG and PCGS.
The TBB Number (The Banknote Book) represents a newer approach, offering more granular classification and a structured, research-driven framework.
A practical distinction:
Pick Number is the market standard for identification and liquidity,
TBB Number provides deeper analytical classification.
Advanced collectors often use both systems together—Pick for universal reference, and TBB for expanded detail and research depth.

Frequently Asked Questions
What is a Pick Number on a banknote?
It is a catalog reference used to identify a specific banknote type in the Standard Catalog of World Paper Money.
What does “P-#” mean?
It indicates the Pick Number assigned to a banknote, with “P” referring to the catalog system.
Can one banknote have multiple Pick Numbers?
No, each distinct banknote type has its own Pick Number, while variations are indicated with suffixes.
Why do collectors use Pick Numbers?
No, it identifies the type of banknote, not its market value or scarcity.
