Hello Here's A Little About My Collection And Me!

Hello everyone I'm fairly new to collecting coins, I mostly collected antiques thru the years and appx. a year or so ago I started collecting coins that I thought were neat. I've done a bunch of reading on US coins mostly, and have a few coins such as Canadian, Jamaica, German, and others that I've found in pocket change. I'm hoping to get some insight on a few of the coins I have and to see the variety of coins other's have. I spend several hrs looking at my coins a week, including my daily take in change from different places I go. For instance today's change I ended up with 2-1959D Lincoln pennies, 1-1959 no mint mark Lincoln Penny,a yellow and red toned 1980 no mint mark Lincoln Penny with what seems to have DDO and DDR. It's in great condition just blurred on both sides. Also I received in my change a Bicentennial '76' D mint mark with what looks like DDR! A couple days ago I found a 2020 no mint mark with a die break, and that is going to be my first upload. I have quite a few that I have questions about and am hoping for some good input and advice, mostly on should I have it graded or not I don't want to waste time and money when it's not necessary. Anyhow have a great day!!!
