For example, a serial number reading would translate to a guitar made on the 1st day of 1978, and it was the 501st instrument stamped that day. This system brought a new level of precision to Gibson dating, yet it was short-lived in its purity. By the mid-1980s, as Gibson changed hands again and moved production from Kalamazoo, Michigan to Nashville, Tennessee, the system evolved again, dropping the explicit "day of the year" logic for a more standard sequential rank. gibson number serial

In the early decades of the 20th century, Gibson was a company defined by innovation and internal disorganization regarding record-keeping. Prior to the mid-1970s, Gibson did not maintain a centralized, computerized database. Instead, serial numbers were assigned in batches, often with little regard for chronological order. 1 2 3 4 5 0 0 0

However, the system was rife with redundancies. Because the numbering sequence often reset or overlapped, a serial number like "9 1234" could theoretically refer to 1959, 1969, or even 1979. This phenomenon is known as the "Serial Number Overlap." To differentiate between decades, one must examine the physical attributes of the guitar. A "9-prefix" guitar with a rosewood fingerboard and "moustache" bridge is likely a J-45 from the late 1950s, whereas a similar number with a maple neck and a volute (a bump behind the nut) suggests the 1970s Norlin era.
