Hey there, I seen "C4S" and thought you were referring to Clips4Sale hence stopping by but then I noticed you state tokens and C4S don't do tokens.
Anyhow, with that being said......from my experience the average clip price point that sells best is around the $5-$8 mark and generally 8-15 mins in length but that is for fetish orientated content. I regrettably don't have much history with mainstream clip content.
It depends on the traffic source being provided/driven as well as the niche of the content. Obviously if you're content is hardcore it's not going to convert well if at all with teen or foot fetish niches.
As with anything, it's all trial and error so stick at it and you'll find your groove.
Best of luck
