How much money is an appropriate wedding gift?

No gift is required for a wedding. Attendance or not. But it all depends on what you can afford. If that is $5, then do that if it is nothing and a card with well wishes do that. If it is $1000, can you be relative? Okay so seriously, give what you feel comfortable giving. My mom always gives $100 to her nieces and nephews. She lives in the Midwest and she can afford to give that.
