Which is more "rare"? Cream Cookie Collection or Honey Cake?

Sooo cream cookie in ivory was for sale on yahoo and it had an ok price as a buy it now so I decided to buy it. Problem is I don't have any money to spend and I really wanted the dress considering its so popular and hard to find at a good price I decided I will just sell a dress or two. Now idk if I should sell my honey cake OP to replace it for cream cookie. I'm sure it'll sell for at least the price I'm buying cream cookie. Or I should sell two "non rare" dresses instead. I ony have 5 dresses atm and Idk if it's better to sell one "rare" dress and still have 5 dresses with one of my dream dresses or sell 2 regulars and have 4 only but have 2 dream dresses. I decided I will sell honey cake but I wanted to know which is considered more "rare". Because id like to know if it's worth it to replace it with CCC
