Definition: A 2x2 (also called a 2 by 2) is a two-inch square holder for a single coin, made out of cardboard with a circle cut into the center of it for the coin, and with a mylar covering to protect the coin and hold it in place (see photo). The 2x2 is the standard cardboard coin holder, and the hole is usually sized to fit the coin exactly. The dealer places the coin between the halves (which are usually joined at one end, so that it folds over) and then staples it in place.
Although 2 inches square (2x2) is by far the most common size, these holders also come in other sizes, including 1.5 inches square, and 2.5 inches square.
The 2x2 holder should not be confused with the flip, which has no cardboard, but two mylar pockets with a paper insert to describe the coin.

Examples: Coin dealers use 2x2's because they are an inexpensive and effective way to organize, store, and display their coin inventory.
