hi,

I am confused with some of these basic comparisons:
(I know it sounds stupid, but... )

Can you please tell me which one is correct and explain why other is wrong?

Dollar coin weights far less than four quarters vs
Dollar coin weights far less than four quarters do

She is shorter than her sister vs
She is shorter than her sister is

I play basketball better than my brother. vs
I play basketball better than my brother does
(I see many similar cases. Sometime requires verb and sometime does not.
can someone please explain this clearly?)

You are more interesting than she. vs
You are more interesting than her
You are more interesting than she is

Here's some idioms:
more x than y: A group has more men than women.
x is more than y: A group is smaller than B group.

Here are my takes:

Dollar coin weights far less than four quarters do

She is shorter than her sister vs
She is shorter than her sister is

I play basketball better than my brother. vs
I play basketball better than my brother does

In all these cases both are correct. in first sentenses the second verb is silent or understood. We need not repeat Do, Does or is as these are understood.
I am confused in the last one. Can somebody through some light on it.

IMO, the second sentences are correct.

the does, is or are at the end of the sentence adds clarity and parallelism to the sentence.

I play basketball better than my brother (what) plays football? eats spaghetti?

I play basketball better than my brother does. ...the does clearly refers to plays basketball

You are more interesting than her.

However,

Mike has more money than Sam.--- here you are comparing money so you need to use

Mike has more money than Sam has.
