Y is last digit of the year (if this number is '3' it is actually 1974). 3 or 4 numerals in center are instrument ranking for year starting with 101. D is body type: D=wood, B=brass, M=steel or mandolin. 1980-1988 OMI Dobro: 8 (#)### yD configuration. 8 is the decade of manufacture (8=1980s). 2 or 3 or 4 numerals in center are serial number for. Sep 28, 2013 There may not be a number on the end of the headstock, as this one was made in the mid 1930's by Regal under license by Dobro. Some of these had serial numbers, and some did not.

Gibson Serial Numbers

some data are taken from the 11th Edition of 'Blue Book of Electric Guitars', By Zachary R. Fjestad
When Gibson start the production of solidbody guitars in 1952, a new serial number system was developed.
5 or 6 DIGITS number ink stamped on the headstock back:
Y NNN(N)
Y= last digit of the year (2=1952, 3=1953, 4=1954, 5=1955, 6=1956, 7=1957, 8=1958, 9=1959, 0=1960)
NNN(N)= production numbers in a consecutive order
4 2205 = 1954
0 9865 = 1960
NOTES: not used on the earliest instruments produced (those done in 1952), a few of these instruments have three digits stamped on the headstock top.
In 1961, Gibson started a new serial number system. It consisted of numbers that were impressed into the wood. This is generally considered to be the most confusing out of all Gibson’s serial number systems used. There are several instances where batches of numbers are switched in order and duplicated, not just once, but up to four times, and seem to be randomly assigned throughout the decade.

Note: If 'MADE IN USA' is stamped in the back of the headstock near the serial number, the guitar is not from the 1960s, but the 1970s.

From 1970 to 1975 the method of serializing instruments at Gibson became even more random. All numbers were impressed into the wood and a six-digit number was assigned, though no particular order was given and some instruments had a letter prefix. In 1970, the words MADE IN USA were impressed into the back of instrument headstocks (though a few instruments from the 1950s also had this).

NOTES: When the Nashville Gibson plant was opened in 1974, it was decided that the bulk of the production of products would be run in the South; the Kalamazoo plant would produce the higher end (fancier) models in the North. Of course, many of the older guitar builders and craftsmen were still in Kalamazoo, and if they weren’t ready to change how they built guitars, then they may not have been ready to change how they numbered them! Certain guitar models built in the late 1970s can be used to demonstrate the old-style, six-digit serial numbers. It is estimated that Gibson’s Kalamazoo plant continued to use the six-digit serial numbers through 1978 and 1979. So double check the serial numbers on those 1970s L-5s, Super 400s, and Super 5 BJBs!
YY= year (99=1975, 00=1976 and 06=1977)
NNNNNN= production number from 100000 to 200000 range.

Between 1997 and late June or early July 2005, Gibson used the same serialization system on all standard-built guitars. This updated system utilizes an impressed, 8 digit numbering scheme that covers both serializing and dating functions.
YY = last two digits of the production year
PPP = plant designation and/or instrument rank:
001-499 --> Kalamazoo production from 1977 to 1984 when the factory closed.
500-999 --> Nashville production from 1977 to 1989.
All currently manufactured Gibsons (non-custom shop) are stamped with a hand arbor, and start at 300 or 500, and continue until production is finished that day. This hand stamp used to be reset daily at #300 or #500
for all the LP style headstocks. The other shapes (Flying V, T-Bird, Explorer, etc.) were started at 700. When acoustic production began at the plant in Bozeman, Montana (in 1989), the series’ numbers were reorganized. Bozeman instruments began using 001-299 designations and, in 1990, Nashville instruments began using 300-999 designations. It should also be noted that the Nashville plant has not reached the 900s since 1977, so these numbers have been
Examples:
70108276 means the instrument was produced on Jan. 10, 1978, in Kalamazoo and was the 276th instrument stamped that day.
82765501 means the instrument was produced on Oct. 3, 1985, in Nashville and was the 1st instrument stamped that day.
03202652 means the instrument was produced on November 16, 2002 and was the 152nd instrument stamped that day (assuming they started at 500).
NOTES: The Custom/Historic/Art divisions do not use this system. Certain models in the Standard series also do not follow this, either.
YDDDYBPPP
B = batch number was implemeted to better keep track of production and allow for more than five hundred instruments to be produced in a day. At the beginning of each day, the sixth digit is reset to 0. Once the last three numbers reach
699, the batch number moves on to 1, and the last three digits are reset to 500.

028360612 stamped on the 283rd day (October 10th) in 2006 and was the 112th guitar stamped that day.
001071520 stamped on the 10th day (January 10th) of 2007 and was the 220th guitar stamped on that day (it was part of the second batch and the 20th guitar of the second batch - first batch was of 200 guitars).
