I don't understand, what were the scammers trying to achieve?

  Maybe hoping there was an affirmative response if the card did go through?

  Trying to validate stolen or generated credit card numbers.

    That's not always what is going on. In some cases unscrupulous operators will run through large numbers of $1 transactions in order to lower their chargeback rate.

      This sounds interesting - can you explain further?

        Chargebacks have a cap, if you go over that cap you get fined or lose your merchant account. So in order to dilute the pool they'll make a lot of low $ amount charges usually masquerading as some charity, those will have very low charge back rates so the average charge back %age will drop.
