That is because the extra 6 tokens goes into the pocket of the Organiiser!!
I think this system may succeed on the following reason.
(I just sold a ML for 2 tokens)
If you r thinking of selling that player, and an offer comes in with tokens, better take it than nothing. On the other hand the buyer is the one that suffer cos he got to pay additional 6 to 8 tokens above what he bids.
