I took over forty dollars worth of coins and put them into a coin machine. The machine is supposed to take 8 percent..I got back $33.69 ?? As the guy said,"Well Stanley, another fine rip-off, you've gotten us into.."" I am wondering if these machines are checked for accuracy? Learned one thing, sort your coins by denomination..Send all quarters, then dimes, then nickels, cents, half cents etc at a time. Should be more accurate, with less "slippage",,,,cordially NAD
