Coins are measured in millimetres.
Millimetres, as in 1.5 mm. You could use a micrometer to measure thickness of a coin.
You could describe that measurement accurately and precisely with any unit of length.But the 'millimeter' would probably produce the most convenient number.

With a micrometer (caliper) To measure the thinkness you use mm's
If the density remains the same and the thickness of the coin is doubled, the mass of the coin would also double. This is because density is mass divided by volume, and if the thickness (volume) is doubled while density remains constant, the mass must double to maintain the same density value.

The thickness is 1.55mm which is measured at the rim of the coin.
The thickness of a two dollar coin is 2.70mm thick.
You would use the metric unit of grams to measure the mass of a dime. This would give you an accurate measurement of its weight.
