worst possible [with 100 points]:
All-Rounders
> ALMEIDA 348/16
> EVENEPOEL 900/18
Climbers
> SKJELMOSE 235/12
> RODRIGUEZ 277/10
Sprinter
> PHILIPSEN 329/12
Unclassed
> GANNA 0/8
> VAN AERT 990/12
Wildcard
> S. YATES 860/12

this should be the least amount of points possible while using 100 coins. stage winners YATES and WVA are the big surprises, but their cost puts them in front of far more deserving frauds like NYS (87/8). 
The worst possible team without any cost limitations is:
All-Rounders
> VAN EETVELT 2/6
> SCHACHMANN 46/6
Climbers
> CRAS 2/6
> CHAMPOUSSIN 16/6
Sprinter
> JEANNIERE 0/6
Unclassed
> GANNA 0/8
> IZAGIRRE/BISSEGER 0/6 [interchangeable with 2nd wildcard]
Wildcard
> BOUVIN/DE BUYST 0/4 [interchangeable with 2nd unclassed]
this would give you a MONSTER 66 points.
