Best to buy tibia coins, they are transferable between servers. Typical ratio is 3-5fg per 1 tibia coin. and tibia coins sell for 10-15k depending on the server. I have sold a few batches of 250 tibia coins for 900Fg ish and 250 tibia coins is between 2 and 4 million on Tibia.
I just sent you 20 fg btw so u better put me as your top donor on your sig.
