Serial numbering

Numeración

Serial numbering is each note’s printed identifier: digits, often with a letter prefix, stamped once or twice. It is the object’s identity in Notofilia. Two papers with the same Pick and different numbering are two pieces. Leading zeros are not stripped when comparing: 00113227 is not 113227. If there are two serials (left and right, or face and back) both are recorded; a mismatch may be a factory error, as on the 2008 50,000-peso note (72461316 / 72411316).

A zero serial on a specimen (00000000) is not a first-of-issue low. A 10000001 may be both binary and a palindrome, as on this collection’s 2008 2,000-peso note. A star beside the number marks a replacement, not a fancy. The City Bank of New Haven and Canal Bank remainders have no filled serial: the No. box is blank, and that absence is documented as no_serial_reason, not invented.

The site’s fancy-serial tool classifies patterns — low, radar, binary, solid, ladder, repeater — on a serial already published. It does not create pieces. The glossary term covers ordinary numbering and points to the fancy-serial article and to records whose serial is the key: R 85688116, F04661756, AA 1955984, J04445744. Each is an object; none is for sale.

Numbering also distinguishes replacements, specimens, and remainders: a star, zeros, a blank box. Treating those three as the same number erases the object’s identity. The linked records — 10000001, Emberá 00113227, New Haven with no serial — cover fancy, replacement, and documented absence. Search indexes the normalised serial; zeros are not stripped when comparing.
