watch who you are attacking a killjoy. and yes the minhag to play dreidel is brought down by the bnei yisochor [or more commonly known as the bnei yisuschor] and the chasam sofer kept this minhag.playing with money there is no makor.
i saw in shu’t mekadeish yisrael on chanukah http://www.hebrewbooks.org/9663 that you should play with pennies so each time you get is less than perutah or you are vadai gomer da`as with a penny that the other guy is koneh. vcholu
what bothers me is in the times of the yevonim they played dreidel when they would be killed if they were caught learning, bzman hazeh we all run away from are gmaras to a game of dreidel. We are still fighting the yevonim
