The closest to that is Sort by Rarity. Sure it is not entirely indicative of the expensive, but typically your Mythic Cards are more expensive than Collector Cards and Collector are expensive compared to Rare.
Alternatively at the moment, you can just go to the Market, sort the cards by price. Cards you own will be indicated by the X1 or so on depending on how many copies you have and use that as reference for an individual card compared to price.
After logging in, go to "My Collection", then click on the table header you are wanting to sort. In your case,"Price" which is the price in the market or via "Total Price" which is the price multiplied by the quantity you have.
