Nickel Coin Plastic Capsule 21.2mm Size Designed to directly fit a US Minted nickel (21.2mm) in the clear capsule, this capsule consists of two separate pieces which can easily be pushed/snapped together. This holder is not tamper evident; should the nickel need to be removed for any reason, the capsule can also be separated with a small amount of effort. The following coins measure in at 21.2mm: Liberty Head (1883-1913), Indian Head/Buffalo (1913-1938) and Jefferson (1938- Date).
