Value of Class B cards

These still seem fairly rare, I've only picked up a couple (none of any use to me).

I looked around on Darkon and couldn't find a single shop selling them, just class C and D.

So took a guess and stuck them in my shop for 2m. They sold, but not immediately. Anyone seen any for sale?

I want some Gpros so I can pierce my shield and wand

B cards can prolly be pawned off for about 10m if you are patient. At least for now while they are still somewhat new.
