The original selling price in Japanese yen is often included in the model number—for example TLS-100 = 100,000 Japanese yen. The higher priced Tokai Gibson replicas have nitrocellulose finishes and long tenon neck joints. Tokai guitars have been made in Japan, Korea and China. Korean production started around the mid-1990s. Tokai guitars made in Korea (MIK) are lower priced guitars, similar to the Korean Epiphone guitars. The MIK (Made in Korea) guitars can be differentiated by the truss rod cover. Japanese guitars have a two-screw truss rod cover whereas the Korean guitars have a three-screw truss rod cover (although some early Korean guitars also have two-screw truss rod covers). The MIK guitars usually have a different Nashville style bridge instead of the usual ABR-1 bridge. Furthermore, MIK Gibson replica guitars usually have a neck made from maple, and the body wood is usually made from either alder, agathis or nato.
Tokai uses a seven-digit serial number usually pressed into the back of the headstock for the Gibson model replicas. Love Rocks use the first digit of the serial number for the year, 10XXXXX=1981 and starting in 1989 Love Rocks use the first two digits for the year, 89XXXXX=1989. Reborn models use only the first digit for the year, 800XXXX = 1978.
There is a major exception to this in that some "Reborn Olds" (very rare) and "Love Rock" models have inked serial numbers on the reverse of the headstock (often referred to as "Inkies"). These guitars are, it is generally agreed, from 1980 (00xxxxx and 01xxxxx) and 1981 (11xxxxx) although there are those who would disagree with this.
It also appears that some of the original 1978 "Les Paul Reborns" have inkied serial numbers
Some MIK Love Rock models have no serial number and simply have "Made In Korea" inked on the back of the headstock. Sometimes the model number may be located under the bridge pickup. MIK Love Rock models identified in this manner include ALS48 and ALS50Q.
It's recent production Chinese. Have you played it? If you've played it and like it and the price doesn't bug you, get it, but it's not an investment-grade instrument. Older vintage MIJ Tokais may be investment instruments, but they're often a lot more expensive - and often worth every penny. (I paid $600 for my 1980 Tokai Tele, and I will never ever ever sell it because it's an amazing player)
