Thank You. I will read the article for sure. So witch coins are worth more. Die variety or mint errors. I found few with errors like no L in Liberty or double die in Lincoln face. I will post them later. When DD is considered worth something ? Because I have quite few already with DD on them. Sorry, I know it can be funny for you but I m totally newbie in that 😜. But even tho I found that so interesting and reading day and night. I found 1982 no mint, small date 3.1g with some DD and errors. I think that one will be worth few $ but I may be wrong. I know already that the most expensive will be D mint, small date and bronze one but the one I have with no D mark, have so many errors. Well , still learning and thank You so much for any advice ❤️❤️.
