Valentine's Day Treats

According to “A History of Valentine’s Day Cards in America” by T.M. Wilson, in 1847 Esther Howland was the first to mass-produce Valentine’s Day cards.  She made them out of lace, paint and expensive paper and each one was individually written by a skilled calligrapher.  The average card sold for $7.50 while others cost as much as $50.  If 10 cents in 1847 would be equivalent to $1.85 today, how much would the average card and most expensive card have cost today?
