The compact 1-1/2" x 1-1/2" Double Pocket Mini Safety Flips will allow you to store a greater amount of coins in a much smaller space, yet are large enough to accommodate coins all the way up to half-dollar size.
The standard size 2" x 2" are rigid with a reinforced edge which gives them added strength and will fit perfectly into 20-pocket stock pages or standard 2" x 2" coin storage boxes. The standard size is offered in a few different material formats for a variety of collecting needs.
The Crown size 2-1/" x 2-1/2" are great for all those oversize items that are just to big to go into the standard size flip. Medals, medallions, you name it and these large Crown size flips will do the job. An information card (flip insert) can be added to these double pocket flips giving you the ability to completely catalog the item with all the necessary information you desire.
The external measurement of 1-1/2" x 1-1/2", 2" x 2", and 2-1/2" x 2-1/2" is an industry standard to allow you to cross reference this holders external size for secondary storage products like vinyl pages and storages boxes. Each product will list the largest diameter coin or medal the holders will respectfully support.
