Drop up to 20 coins into the hopper....and watch as the Cyber Sorter sorts and electronically counts coins rapidly into the waiting coin tubes showing a grand total on the digital display. With the press of a button you can see how many dime, penny, nickel and quarter coins are in each tube. After a moment the display will return to the grand total coutned. Coins may also be subtracted from the total. A handy, easy access overflow tray collects all coins that spill off the top of the full coin tubes. After sorting, pull the coin drawer forward to remove full rolls of coins. Requires two "AAA" batteries and two "C" batteries (not included).
