Coin size guide

Find the right capsule for your coin

Measure your coin across its widest point in millimetres, then find it in the chart for its country below. Every coin listed is one we stock a holder for, so you can go straight from the chart to the right product. A direct fit capsule is moulded to a single coin size. A black ring capsule frames a smaller coin inside a larger display body.

Coin diameters vary slightly between issues and years. Where a coin sits at the upper limit of a capsule, measure first. Some thicker coins are noted as a snug fit. If you are not sure how to measure, read how to measure a coin.
