Don't see your coin/bar listed above?

To find the right coin capsule size, measure your coin's diameter (width) and thickness (height) using a ruler or caliper. Place your coin flat on a ruler and measure across the widest point for diameter. For thickness, measure from the top to the bottom of the coin when it's standing on its edge. Compare your measurements to our size chart above to select the proper fitting capsule. A snug fit protects your coin while allowing easy insertion and removal.
