As far as I've seen and we've commented on this recently Quality goes up with the Token price (I'm sure its been covered in the past too before my Forum Birth). I recently had a 15T youngster that was 3* but quite close to 4. I've signed and sold a 9 or 12T (can't remember now) youth that was just over 3*. So you can expect higher token prices to be at ascending Qs in the 4* range.
