I think you’re better off either buying them or don’t, having the coin in hand rather than asking questions from a photograph. I am sure everyone on the forum who collects copper/bronze from a picture has thought the coin was something it wasn’t. Hope that makes sense, people have looked at bronze pennies for years and although hundreds not recorded it’s because the tiny differences are not really relevant. Cgs when they were slabbing pennies had over 80 just for 1860 and if you want to take it so far then my own opinion is your doing a lot of work finding and buying pennies that nobody else would be interested in. Maybe study the Gouby book as there are plenty in there recorded that you can look for and recorded being more than one of each rather than something struck in error like a random flaw, dot or die crack or tiny difference in date width. As I mentioned you can take it as far as you want, just ones like 1902 pennies there are over 20 and yet most you can’t see with the naked eye 😃
