not many people are looking to buy CdM goods, and I don't know anyone crazy enough to buy basil
No, but her plunderees might.
When I was in Iron Age, I asked a couple dealers if they sold CdM sets. I was quoted 150 and 200, which seemed high considering that Traz goods are going for 200. I advanced to EMA and slowly traded up for the goods - took about six weeks, and that was only possible because I had some friends who moved up to LMA.
Anyway, considering that it costs 5000 diamonds to buy 1000 LMA goods, and 50 diamonds to buy a FP, my best guess is 100 FP.
