Some quick calculations show that in theory this is actually worth more (in terms of real cash) than the standard 300 Glory UR bundle.
However, my premise for valuing cards is not necessarily correct. What I currently do is say 1 copy of a card is equal to roughly 10 of the lowest quality keys (so generally Glory, but in this case Gold). And this is skewed a bit further by the fact that buying gold for real money is actually a very expensive way of getting gold.
