Citibank Platinum Select Visa Chase Platinum Master Card MBNA Platinum Visa Discover Platinum AMEX Optima Platinum AMEX Blue Household Bank Gold Card Providian Visa Card I'm thinking of getting rid of a few of these cards, but will this hurt my overall credit score? I have a $300 balance on my Blue card, but I paid off the balances on my other cards some time ago. How many credit cards are recommended to get a high score? By the way, none of these cards have annual fees. Thanks.
