An essential coin folder for penny collectors To do its part in the war effort, the U.S. Mint changed from a copper cent to a zinc-coated steel version for one year, in 1943. Rumor quickly spread that anyone who found a 1943 copper cent would be rewarded with a car from Ford. Now you can display your collection of the legendary Lincoln cents of 1909 to 1958 in this beautiful four-panel coin folder. Larger in size than the average folder, this unit has room for 144 coins, the most of any similar folder.
