Hello There Coin World

I am generally new coin collecting or perhaps I should say I just started actually collecting them I've known a little bit here and there about coins but never got serious until I found a 1950s real silver quarter and started noticing here and there I would get a hold of several wheat pennies and whatnot I find in my change now I look through every single thing because there are so many valuable errors and normal coins that you would just pass unless you know you're what you're looking for and I think it is really cool hope I find something awesome definitely think it's cool to get hooked up with a community forum so maybe I can get help figuring out things that I find because I'm still coin illiterate I have a moderate collection wheat pennies and a few coins that I think maybe error coins I also have a penny that I think is quite valuable but I'm not sure how to figure out what it's worth other than looking online and seeing what people have said about them like right now I have a nickel I've never seen before on any site with an error that I think is one of a kind but I have no idea how to figure out officially if that's true
