I have read too many conflicting articles across the internet, and since I know I talk a lot I'll bullet point them in case someone only feels like answering one of the confusing questions I have. If there's a 1900 coin with some defects but still in incredible shape, definition, strike, toning, no toning, etc., will it be graded differently than a 2000 or 2020 coin in identical condition? I have never seen a MS 100 (I'm exaggerating again), or near perfect coins. Are there any perfect coins? And proofs? How can you know the difference between a proof coin that has been released into the wild and a coin with exceptional deep striking (is this cameo/cam)? I sometimes find coins that are what I would call "frosted ". They're not dull, not toned, usually well struck, but look like someone painted it with frost spray paint. Is this a modified coin or do the mints make some this way? I see some just the opposite that look like someone dipped them in reflective/shiny clear polish but they're always 100% perfectly uniform. No missed spots, no globs or places with more shine than any other place on the coin, and no discernable points where it had to be held when it was clear-coated. How or where is this done and is it a good or bad thing? Is the ring around a cent a collar, edge, frog boogers.... ? I see a LOT of the more recent cents missing most or all of the collar/edge/whatever. Is this normal? If they are normal, what happened? I have numerous mangled beyond all recognition cents, and some with cuts, scrapes, abrasions on one or both sides. How can I confidently understand the difference between error coins and after the fact post mint abuse? I didn't want to bother anyone with stuph I can research for myself and I've tried finding the answers to these things. But that's the problem. Too many different answers. Thanks for any wisdom you are willing to donate.
