Mmm I normally give money as a gift anyway but I get a bit shirty when people ask for it specifically, Id rather they have a register, I know its easier with money but then it puts some people in a bit of a bind.. as for the $50 - thats fine as an amount, its whatever you can afford, and any amount is appreciated. What you can do, is perhaps by a nice picture frame or two large candles (from a variety/two dollar shop) and put them in a small box with some tissue paper, rose petals, and a handful of wrapped lollies or choclolates (this signifies you are wishing the couple a sweet life together) and put your card in the box and nice big bow over the top. That way you can still spend $60 and it looks like you have spent a bit more and put in extra effort which im sure they will appreciate more than the actual dollar amount...
