Sentence "I only have some dollars"

I only have … dollars.

(a) some
(b) any
(c) a little
(d) a few

I can’t understand what’s wrong with the sentence “I only have some dollars”. And by the way wouldn’t the sentence “I only have few dollars” be correct as well?

Thank you in advance.

I only have a few dollars, is the correct phrase.

Sorry, but I still can’t understand. Is anything wrong with the following sentences?:

I wanted to buy something in the airport shop, but all I had were some dollars and the shops would only accept euros.

I wanted to play the nickel slot machines in Las Vegas, but I did not have any five-cent coins; the only coins I had were some dollars I had won the previous day in the dollar slot machines.
