First off, I have to acknowledge Voidoid56 for showing me how to date pots. It seems he created a monster and began quite a journey for me. His forensic work on Tokais and other MIJ guitars is inspiring.
For me, I think it all began with a six digit serial number Breezy someone was asking to date and Voidoid56 shared how he had dated some guitars with the pots,
Help confirming 1984 Breezysound
and that combined with Peter Mac commenting on when the hyphen or - symbol began, just fed my curiosity.
But the mystery of that guitar and the tools used to sort it out stuck with me.
As I applied these same tools to other guitars, some common themes emerged and began to fit together.
As a side note, the = sign persists into 1987 at least as a mixed code where it is used with the - sign. Usually = on the body and - on the neck, but I have seen the opposite as well. Always matching numbers. Never two = codes
Mixed Codes = & -
Note: I wanted to reach out with an appeal at the bottom of this post for specific help with the remaining puzzle pieces.
TIMELINE (1981 - 2009)
1981
It is starting to look like there was an alternate serial number system for non reproduction Fender style guitars beginning around 1981.
The serial numbers begin with 1xxxxx
The first one I have seen seems to be Breezys that are non reproduction models with humbicker pickups and trem bridges.
Breezys With Tremolo & Humbuckers 6 Digit Serial 10xxxx
1984/85
It seems hit and miss between 1981 and 1984/85 when it starts being used again and more often on unconventional models with Fender style bodies.
Six Digit Serial Numbers Starting With 11xxxx
1986
The Fender serial number system apparently ends in the spring of 1986.
Fender Style Serial Numbers Ended When?
And as the Fender system ends a different 6 digit serial number system appears.
It begins with 2xxxxx.
Six Digit Serial Numbers With 2xxxxx
After logging examples of these 2xxxxx guitars along with the pot dates, I figured out that the first number of the production code is most likely the month as felixcatus and togps had claimed years ago to have gotten directly from Tokai.
Note however that there appear to be times when the neck plates are out of sequence with production, in clusters as though a box of plates was found months later.
1987
Brass ground plate gone before February, maybe January.
1989
After the 2xxxxx system there is possibly a short lived five digit system starting with 1xxxx. Still looking for pot dates to corroborate this.
Five Digit Serial Numbers 1xxxx 1989
1990
Around 1991 another system begins. A six digit system starting with 01xxxx.
This system goes until after the pots with readable codes are stopped being used in 1991.
The next pots have two black ink lines of text: Made In Japan and pot value.
Many of these 01xxxx guitars are HSS bodies.
Six Digit Serial Numbers Starting With 01xxxx and Mystery HSS SSH Goldstars
Gray backed pickups have disappeared by now, and the pickups now used are black backed. Some seem to have black & white lead wires (MKII ?), but the most common ones are lower spec pickups with light gauge red, white & blue wire. These persist into the mid 2000s.
Mystery 1990s Single Coil Pickups TOS1K or MKIII ?
Most of the guitars in this period are low spec with inexpensive wiring and pickups as shown above; however, there are some examples of a high spec Goldstar with eboy fretboard and bird's eye maple neck and one piece ash bodies.
Very Unusual High Spec Goldstar, Custom Build?
1992
After 1991 the pots with dates dry up, so dating Goldstars after this is less of a science and more of an art in piecing together associations.
The Fender Years
It’s my opinion that Tokai began making guitars for Fender at this time and continued to for much longer than most people believe. The facts of the relationship apparently protected by a non discluure agreement.
Tokai Built Fenders
It is notable that at this time the serial numbers and indeed production of ST guitars in Japan virtually ends. We then see low spec models apparently made for Tokai in Korea while Tokai is making Fenders.
2000
There are two more periods where we definitely see some MIJ Tokai ST guitars, but neither have serial numbers.
One "no serial" Tokai period is marked by all caps "MADE IN JAPAN" inked on neck heels apparently around 2004,
All Caps MADE IN JAPAN No Serial Number Guitars
Countersunk holes in the neck pocket disappear during the all caps period.
The other no serial period for MIJ St guitars is marked by the use of ink stamped upper and lower case "Made In Japan" on neck heels around and including 2009.
No Serial Number MIJ Goldstars
2009
At the end of 2009, in October I believe, serial numbers return. This time inked on the neck heel curiously similar to Fenders. They are date based numbers including production year. That continues to this day.

Appeal
So here is part of why I am sharing this. I would love help in filling in blank spots. I know many of you have logged all sorts of data on these guitars. Would love it if you could share some of what you have gathered to help with this puzzle.
Here is a list:
- Pot dates for six digit serial number 11xxxx guitars.
Six Digit Serial Numbers Starting With 11xxxx 1986 ?
- 1988 pot dates with pot codes.
- Pot dates for 1xxxx guitars.
Five Digit Serial Numbers 1xxxx 1989
- Pot dates for 01xxxx guitars.
Six Digit Serial Numbers Starting With 01xxxx 1991 1992
- Fenders with Tokai features (countersunk holes in the neck pocket, hyphen product codes).
