Kiyo, I think you meant 3-5k each on the blank cards lol.
But honestly, I think you'd get more bang for your buck just turning the things in with the GM-NPC :x
PC> Raydric card
PC> Ice Pick (Range of prices appreciated)

More as a FYI to Roger who is usually the one answering, but lot of people seems very willing to part their Scalpels at 300k only. Perhaps there's a lack of buyer. When I offered to buy it at a lower price than the PC here, people are very willing to jump at the opportunity~
