There are certificate notes and red seal notes but they're not the same, at least among bills issued during the 20th century.
Red ink indicates that a bill is a United States Note. Certificates were at issued for redemption in silver (blue seal, up to the 1957 series) and gold (gold seal, up to 1928)
US Notes were simply a different form of currency that was almost identical to modern Federal Reserve Notes. The only major difference was that they were issued directly by the federal government versus the Federal Reserve System. US Notes generally made up only a small fraction of all bills printed each year, so they were phased out between 1966 and 1971 in order to eliminate the costs of maintaining two separate production lines.
There were no $5 silver certificates issued with that date. 1928 US $5 bills were printed as either red-seal US Notes or green-seal Federal Reserve Notes. Please see the question "What is the value of a 1928 US 5 dollar bill with a red seal?" and "... with a green seal?" for more information.

See the question "What is the value of a 1928 US 10 dollar Federal Reserve Note?" for values.

Actually, in would be VERY surprising if a red-seal $2 bill had the words "silver certificate" on it. The last red-seal $2 silver certificate was printed in the 1896 series. By the early 20th century most seal colors had been standardized with red used on United States Notes and blue used on silver certificates. I'm sure if you look at your bill again it'll have the words "UNITED STATES NOTE" in a banner across the top of the bill's front. For a more specific answer about its value, please search for questions like "What is the value of a (date) US 2 dollar bill?", where (date) is the date on your bill.
