The title of the “smallest coin” can be interpreted in a few ways.
- The Croatian 2022 1-kuna coin “Hum” holds the Guinness World Record for the smallest commemorative coin ever made.
- It measures a tiny 1.99 millimeters across and weighs just 0.05 grams.
- It’s so small you’d need tweezers to handle it.
- In the United States, the coin with the smallest value is the penny , worth one cent.
- However, the dime (10 cents) is actually physically smaller than the penny, with a diameter of 17.91 mm compared to the penny’s 19.05 mm.
- The U.S. Mint highlights this difference by making the dime a different color (silver) and giving it a reeded edge to help distinguish it from the penny.
- Historically, other extremely small coins have existed, such as the Indian Bele from the Vijayanagara Empire (14th-17th centuries), measuring 2-3 millimeters across.
- The Panama 2.5 centesimos (the “Panama pill”), minted in 1904, had a diameter of just 10mm.
It’s important to remember that determining the absolute “smallest” depends on the criteria used (diameter, weight, value, historical context).
