Our Canadian cardboard 2x2 coin holders are made in Canada as the name suggests. To use these cardboard 2x2s simply place the coin in the holder, fold over and staple shut. These holders come in seven sizes, one for each denomination of US coins. Each are coated in a clear film that helps prevent moisture and dust from entering the holder and damaging coins. We are proud to offer these in packs of 25 and 100. We also have great storage solutions for cardboard holders such as a variety of storage boxes and pocket pages.
