Which of the TCG Batman cards are most valuable? Black Bat, Red Bat or Blue Bat?

For whatever reason Black Bat card 1 and 2
Have been getting insane prices.

I cannot really answer the question outside of that. My son has been working on these sets plus the riddler back and bat laff as well as
The Maclean’s toothpaste Batman cards.
Ungraded he has the most of Black bat then Red then bat laffs then blue and no Riddler backs.
He says the most he pays for ungraded is 2 bucks a card.
Graded his max is around 10 dollars. He has the most bat laffs then. Blue bat then riddler backs then red then black bat graded.

My guess is they are all about the same.

I am finding that the Bat Laffs and the Riddler backs are the more difficult cards to find. The others seem to be more common, although condition is always a factor. Price-wise, I find them all to be going for about the same amounts.
