When You Examine Canceled Checks Returned in the Bank Statement

Essay

When you examine canceled checks returned in the bank statement by a client's bank,how could you tell whether the amount on the check had been skillfully raised (increased,say,from $75.00 to $7,500 in the amount box,and altered in the written line from "Seventy-five dollars" to "Seventy-five hundred dollars")after the check was cleared by the bank? (An employee might do this to "support" a $7,500 cash disbursement journal entry.)
