Without seeing photos of the guitar itself for verification it looks to me like you have a USA-built '52 Reissue Telecaster that was assembled, inspected, and sent to the warehouse on July 7, 1988 - per that Certificate of Authenticity dated 07/07/88. Unfortunately while Fender has a searchable serial number database it only goes back to 1993 (I believe they changed computer systems at that time and the old records were filed and not uploaded).
Now until the latest version of the American Vintage '52 Tele came out in August of this year the USA-built '52 Reissues shipped from the factory with what is known as "vintage wiring" just the way Teles were wired from circa late 1951 until the mid-1960s (1967 I think). In vintage wiring the 3-way switch gives you these three settings:
Position 1 (switch pointed toward the bridge): bridge pickup with the tone control active
Middle position: neck pickup with the tone control active
Position 3 (switch pointed toward the neck): neck pickup with a treble roll-off capacitor (kind of a muddy sound) and the tone control inactive
The USA Reissues came with a kit and instructions to change the guitar to "modern wiring" which gives you these three settings:
Postion 1: bridge pickup with tone control active
Middle Position: both pickups with tone control active
Position 3: neck pickup with tone control active
Now you will have to tell us if the previous owner of your Tele had already made the change to modern wiring - does the switch work like the vintage wiring or the modern wiring? The wiring diagrams are one for vintage wiring and one for modern wiring.
These also shipped with the accessory bridge with 6 saddles and instructions on how to install it.
Now to your other questions. In 1952 Fenders did not have any country of origin marked on them because all Fenders were made in Fullerton California. The USA-built Reissue models also do not have a country of origin marked on them to be accurate to the original year. Also in 1952 the serial number was stamped onto the bridge plate - it would be the third line on the bridge (first line says "Fender", second line says "Patent Pending", third line is the serial number). The blank neck plate, slotted screws, bridge pickup mounted directly, nothing on the back of the headstock etc. are all hallmarks of how the Teles were built in the early 1950s - except for the missing switch knob of course.
Since this is a 1988 model, it would have been called the "U.S. Vintage Reissue 1952 Telecaster" and it would have been built in Fender's Corona, CA plant (Fender changed ownership in 1985 and they didn't buy the old CBS-era factory in Fullerton; the built a new factory down the road in Corona). As a 1988 I don't believe it has any extra value over a later one. It seems like only the CBS/Fullerton Reissues from 1982-1984 and the earliest Corona Reissues (1985-mid 1987) have escalated in value; by 1988 FMIC/Fender was really into full production mode on both the USA-built reissues and American Standards/Plus models so they don't carry the premium of the earlier ones. I would call this a player so you can do what want with it.
