Welcome to the forum macki. You've come to the right place to learn. There are many very knowledgeble and experienced collectors here that are willing to share what the know those new to the hobby.
That being said, one thing you will here repeated alot is that it is very difficult, if not impossible to judge a coin without seeing it. In hand is better, but a digital photo will go a long ways here
I'm not the most experienced here, but many of the coins listed sound common as errors go and unfortunately don't command a premium. Most of them sound like die-fills, die-chips, and/or strike throughs.
Some of them though do sound promising, but again, without seeing the coins, I'm just guessing at some of previous owners shorthand/notations.
Again, I'm not an expert so will let the "resident experts" at this forum chime in.
