There are two kinds of Jewish menorahs. The six-branch menorah with a seventh center candleholder is used in Jewish temples. The Hanukkah menorah, used only during the eight-day holiday, has eight branches and a special central candleholder. Each day, candles are lit to represent the day of the holiday--one the first day, two the second day, etc. The single holder in the center is for the special candle that is lit first, then used to light the other candles. Prices for antique Hanukkah menorahs are usually higher than prices for antique temple menorahs.
