By principle of mathematical induction any number can be written as a sum of distinct powers of 2. For proof :(http://faculty.salisbury.edu/~kmshannon/math300/distinctpowers.pdf)

Hence the bags should contain,
1st bag = 1 coin
bag2 = 2 coins
bag3 = 4 coins
bag4 = 8 coins
bag5 = 16 coins
bag6 = 32 coins
bag7 = 64 coins
bag8 = 128 coins
bag9 = 256 coins
bag10 = Remaining 489 coins
