Post a full pic of the obverse and reverse of each coin in its own thread with a clear explanation of what you think you see along with a description of the research you’ve done for each coin already (sites visited, comparisons, etc. )
I dont see anything on the quarters but wear and tear. The Lincoln cent has common die deterioration wear causing that ridge you are seeing. The nickel is just damaged from being at the end of a roll of nickels.
