I am new at this. I've been trying to learn all that I can from various websites but I am still struggling with identifying errors.  I really cannot afford to take my coins for appraisal.  Where else can I go to get some help? BTW, I live in Colorado Springs, Colorado.

You could take your coins to the American Numismatic Association, there address is 818 North Cascade Avenue Colorado Springs, Colorado or you could attach an image on the ANA member forum. A helpful website is https://conecaonline.org/
