1 Raw iron is found in earthâs crust, as an ore. 2  Iron ore mostly found as Fe 2 O 3 (the form of iron oxide found as the mineral hematite).
A US quarter struck in 1964 or 1965 (dated 1965) and later weighs about 5.67 grams. A US quarter struck between 1930 and 1964 weighed 6.25 grams. This would make a roll of qâ¦uarters, or 40 quarters, weigh between 226.8 grams and 250 grams. This is about half a pound for the lower figure and almost 1 ounce more for the higher figure.
Update: Dear JustAskin: I don't have a roll of quarters in front of me to take apart and count. I was asking how much money I need to take with me to the bank in order to get a roll of quarters. Congratulations on being the first ***! Follow. 21 answers 21. Report Abuse.
