In a sentence, dollar and cent amounts should be written out in words, such as "sixty cents" or "thirty dollars". Alternatively, the number value may be written in digits or figures, such as "60 cents" or "30 dollars."
Some style guides have different rules pertaining to the use of numeric figures. The "Associated Press Stylebook," for instance, recommends spelling out the numbers one to nine and using figures for any number higher than (and including) 10. The "Chicago Manual of Style," on the other hand, recommends spelling out all numbers less than 100. In any case, it is not recommended to use "$0.60" in a sentence.
