CAIRO, Nov 26 (Reuters) - Egypt's pound held steady at a central bank dollar sale on Wednesday but strengthened slightly on the unofficial market.

The bank offered $40 million on Wednesday and said it had sold $37.6 million at a cut-off price of 7.1401 pounds per dollar, unchanged from its last sale.

The rates at which banks are allowed to trade dollars are determined by the results of central bank sales, giving the bank effective control over official exchange rates.

In the unofficial market, the pound was trading at 7.63 to the dollar, slightly stronger than Monday's rate of 7.65, one trader said. (Reporting by Shadi Bushra; Editing by Toby Chopra)
