It is more common to hear a British-English speaker say "one thousand two hundred dollars" than "a thousand and two hundred dollars", although the latter construct is common in AmE. In British English, the "and" comes after the hundreds ("one thousand, two hundred and thirty dollars"). The term "twelve hundred dollars", popular in AmE, is frequently used in BrE but only for exact multiples of 100 up to 1,900. Speakers of BrE very rarely hear amounts over 1,900 expressed in hundreds, for example, "twenty-three hundred". In AmE it would not be unusual to refer to a high, uneven figure such as 2,307 as "twenty-three hundred and seven".
