<p>A coin stacking means for stacking coins to be wrapped includes a pair of stacking block means (8a,8b) each being movable relative to the other perpendicular to the direction in which a coin sorting passage (4) for passing coins of a predetermined denomination therethrough extends. The first stacking block means includes a first inner wall section lying at an angle X to the direction in which the coin sorting passage extends and a second inner wall section lying at an angle -X to the direction in which the coin sorting passage extends. The second inner wall section is higher than the first inner wall section in the direction in which the coins are stacked. The second stacking block means includes a first inner wall section and a second inner wall section. The first inner wall section thereof and the first inner wall section of said first stacking block are formed symmetrically with respect to the center line of said coin sorting passage, and the second inner wall section thereof and said second inner wall section of said first stacking block are formed symmetrically with respect to the center line of said coin sorting passage. The second inner wall section thereof is higher than said first inner wall section thereof in the direction in which the coins are stacked. <IMAGE></p>
