Watermarks, security strips, and microprinting weren't introduced until the 1990 "big head" redesign.
Older bills have very few anti-counterfeiting features. The most obvious is the presence of small red and blue fibers embedded in the bills' paper.
I believe the watermark began on the 1990 series so no 1988 was still too old.

What is a 1950 one hundred dollar bill without "In God We Trust" worth?
It should have a portrait of Benjamin Franklin in the center of the bill. If you're referring to the watermark of Franklin, that wasn't added until series 1996.
