Mostly we talk about the value of something in present tense using the present stem of " ارزیدن" which is " ارز " and put " می " at the beginning of it and add the verb id " ـَ د " at the end; " می ارزَد "
For example: این مِداد 10 دلار می ارزد.
( This pencil is worth 10 dollars.)
Also, we can talk about the value of something in the past tense.
For example the value of your first car or your old house etc.
In this case we use the past stem of " ارزیدن" which is " ارزید " , then add " می " at the beginning of it. That's it. Now use it in the sentence as follows:
ده سال پیش، آن خانه دو میلیون دلار می ارزید
( Ten years ago, that house was worth 2,000,000 dollars.)
