Hello I am new in coin collecting, I just started early this month (June) when I was watching youtube and there's this video regarding valuable pennies and I saw the year 1982. Recently I found two 1982 pennies with
no mint marks on them with big dates (I guess) and both weigh 3.1 grams. On the videos and the articles that I read so far only mentions 1982-d and small dates are the only ones with significant values, does this means the 1982
no mint mark and weigh 3.1 grams has no values? I would love to hear from any community member regarding this matter for it be my very first step in learning something for my coin collecting journey. Thanks
