Your bill sounds like it might have a "flipover" error. My advice would be to have it examined in person by someone who deals with error currency because auction values can exceed $300.
Bills are printed in multiple steps on large sheets of paper. A flipover error can happen if someone accidentally feeds a sheet in the press upside-down and/or backwards.
No mint mark means the coin was minted in Philadelphia.
1928 $2 bills were issued in 8 different series variations identified by a small letter (or its absence) near the date. Please check for the letter, then see the question "What is the value of a 1928 [letter] US 2 dollar bill?" for more information. The red seal and serial numbers simply mean that the bill is a United States Note, a form of currency that was printed up till the 1960s.

Serial numbers are counters and a security feature but usually don't help to ID a bill for valuation. Please post a new, separate question with the bill's date and what letter if any is next to the date. Some collectors will pay extra for numbers with a special pattern, e.g. 12345678, or low numbers such as 00000015.

Please check your bill's denomination, date, and what letter if any is next to the date, then enter the question "What is the value of a (date) US (denom & letter) dollar silver certificate?" - for ex. "What is the value of a 1934 D US 5 dollar silver certificate?" Some collectors will pay extra for numbers with a special pattern, e.g. 12345678, or low numbers such as 00000015.
Letter e with numbers denotes exponential figure.
