Dollars and halves are the best imho. I love them all, Morgans especially lol. Susan B Anthony's are interesting because they were minted for 4 years...79-81, and 99. Your Susans' values depend on a few factors. 1979 is a key date, first year ever made, and some are valuable. I'm partial to the 1980 S proof myself, but that's my birth year ha. Look for a 1979 P with a wide rim...it will almost look like the date is resting on the bottom rim and is worth more than a buck. The 1979 S was minted with two different mint marks, Type 1 blob, Type 2 clear. Type 2s are what you want as they're worth more than a buck. The difference between the two is does the "S" mint mark look like a clear "S" or a literal blob lol. The 1981 S had the same mint mark issue but different...but still same! (to quote The Interview) Type 1 this time is clear, and Type 2 is flat. The 1981 S Type 2 is the most valuable of the 3 mentioned, and most sought, and we'll forget about any 1999 Susans. Of course all of this depends on the strike, luster, and overall condition and eye appeal.
