Sounds like something from the World Monetary Reserve, a private outfit that packs ordinary circulation coins in special holders they call "ballistic rolls" and sells them at significant markups.
However most of what I've heard tells me that "ballistic" actually describes how people go when they find out that they've paid 3 or 4 times as much for these coins as compared to just getting them from a local bank.
I have a Ballistic Roll of James Monroe coins and it has 50 coins in it.
425 grams is 425,000 milligrams.
425 grams is 0.936965 pounds.
425 grams = 0.937 pounds, approx.
1000 grams = 1 kilogram so 425 grams = 0.425 kg. Simple!
0.425kilograms
A cup of flour is about 125 grams. 400 grams is therefore about 3.1 cups. 425 grams is about 3.4 cups. You might be ok with about 3 and a quarter cups. But adjust as needed.
Divide by 1000.
That is 14.991 ounces
That is 15 ounces of butter.
14.928 ounces
Sorry, but no U.S. coin contains 425 net grams of anything. Please be more specific and post new question.
