1947 S Penny Errors?

Hi. Railroad coin? How can I find out the mist info on coins. How does one know railroad coin info or what that is. Trying and want to learn all I can to be a expert in this field I enjoy this so much. I got hurt really bad about 2 1/2 years ago. Several surgeries. Severe head injury etc. this has and is helping me relax and try to stay focused on something. I was laying around and pretty much deep depression setting in etc. It keeps me busy for many hours and not to hard on the body. Lol. I have my own construction business and pretty much need a new career. Several knee and back surgeries and can barley use my left arm and hand so construction is very hard lol. Anyway, any help you can provide me on day sites and places that are best for learning and materials needed or should have for a beginner just starting out. Apps or programs for higher quality pictures and identifying the errors on the coin( like adding text and ability to circle the areas ) I see pictures posted that are so vivid and clear and also super close ups with no pixel distortion. How? What Can I get to do that?

Lmk
Thanks
