Money & Coins
Coins are the most precisely weighed objects most people ever touch. A mint that is off by a hundredth of a gram is a mint with a problem, so every denomination has a published specification down to the milligram.
Banknotes are the counterintuitive half. A single bill weighs about a gram — which means a briefcase of cash is far lighter than the movies suggest, and a million dollars in hundreds fits into 10 kilograms.
Lightest: US one dollar bill (1 g) · Heaviest: 1 oz Krugerrand gold coin (33.9 g)
| Object | Weight | Imperial |
|---|---|---|
| US one dollar bill | 1 g | 0.04 oz |
| US nickel | 5 g | 0.18 oz |
| US quarter | 5.7 g | 0.2 oz |
| 1 euro coin | 7.5 g | 0.26 oz |
| 2 euro coin | 8.5 g | 0.3 oz |
| 1 oz Krugerrand gold coin | 33.9 g | 1.2 oz |
Money & Coins: frequently asked questions
How much does a euro coin weigh?
A 1-euro coin weighs exactly 7.5 grams and a 2-euro coin 8.5 grams — both fixed by EU minting specification. Coins are among the most precisely weighed objects you will ever hold.
How much does a dollar bill weigh?
Almost exactly one gram — and every US note weighs the same, regardless of denomination. That's why a million dollars in $100 bills comes to 10 kg, while the same million in singles would weigh a full metric ton.
Does a one-ounce gold coin weigh one ounce?
Not quite. A Krugerrand contains one troy ounce of gold (31.1 g) but weighs 33.93 g in total, because it is alloyed with copper for durability. The gold content is exact; the coin is heavier than its name suggests.
What are the lightest and heaviest money & coins objects in the game?
The lightest is US one dollar bill at 1 g (0.04 oz), the heaviest is 1 oz Krugerrand gold coin at 33.9 g (1.2 oz).
