Does a 1988 one hundred dollar bill have a security strip in it?

No, a 1988 one hundred dollar bill does not have a security strip. The security features, including the security thread, were introduced in later designs of the hundred dollar bill, specifically in the series released in 1996. The 1988 note features a different set of security features, such as a watermark and color-shifting ink, but lacks the security strip found in newer bills.
