He means the cardboard holder the coin is in (2 inch by 2 inch). Coin collectors all use them today, but they've likely been around since the advent of cellophane in 1912.
The coin shop I frequented as a child in the late 1970's would hand out steel cents in 2x2's like this, at Christmastime, to advertise the establishment. The wartime steel cents looked so striking, people kept lots and lots of them as mementoes in the 40's, so they are quite common. Makes for an eyecatching but cheap advertising ploy.
