I moved on to the $15 I got from one of my other banks. That is all they would spare since they said a local fraternity had a charity event that collected pennies and wiped them out. Anyhow, I weigh them. All rolls are 133 to 141 grams. Full copper roll weighs 155 grams. They were running around 25% until I hit one batch of 4 rolls that had 38% copper including an 1890 indian head


That was my first indian head find and I yelled when I slid out the coins and saw it. My kids came running. Pretty cool.
My normal percentage around here is 25%.
