Ranking numbers for Bozeman start each day at 001 and the electrics may start as low as the 300s.
The sixth number is now a batch number- batch 0 starts at the beginning of the day, and once we stamp 699, the batch number will change to 1.
The pattern is as follows: is the production year is the day of the year is the plant designation and/or instrument rank.
Plant designations are as follows: 001-499 = Kalamazoo 500-999 = Nashville (300-999 from 1990-present) 001-299 = Bozeman, Montana (acoustics only starting 1989) * Kalamazoo numbers were discontinued in 1984.
The transfer contained an eight digit serial number as well as "MADE IN USA". There also were some bolt on models with a date ink stamped on the heel.
Gibson introduced the current system of serialization in 1977 and continues with it today.
But the serial number on a Gibson can tell you when the guitar was made.
With that information, you can determine its rarity and, ultimately, its worth. For acoustic instruments, the serial number is typically located inside the sound hole at the neck joint or on a piece of paper glued inside the guitar and visible through the sound hole.
For information on FON numbers a copy of The Blue Book of Electric Guitars by Zachary R. For the most accurate identification contact Gibson.
There should be a space after the 1st digit with the 4 and 5 digit serial numbers, and no space with the 6 digit numbers.
The 1st digit indicates the year of manufacture for the 4 & 5 digit serial numbers, these were used from 1989-1999.
New white and orange rectangular labels were designed for acoustics and smaller black/purple and white labels for hollow body electrics.
From 1975-1976 a transfer was used for the serial numbers.The 1st and 2nd indicate the year of manufacture for the 6 digit serial numbers which we've been using since 2000.
