I Don't Know Which Of My Coins Are Worth Keeping. Are There Any Guidelines On Which Ones Have Good Value?

Your coin is more likely to have better value if it meets these general guidelines:
1) Is it made of silver? or gold?
2) Is it older than 1940?
3) Is it in mint state, fresh condition?
4) Is it free of defects such as fingerprints, dings, scratches, stains?
5) Is it a lower mintage date than others in the series?
6) Is it a sought-after error or variety?
Of course, there may be exceptions but the exception would still meet some of the guidelines above.
