If you become a paying member of BF ($10 a year I think), you can sell on the C&V for sale forum and escape the eBay fees. These will sell.
I really like those competitions and they are worth more, especially with those brake levers, than the racers.
I've been buying mafac racers on and off. Clean sets tend to go for right around $35 on eBay where prices are high for anything "vintage." Clean and new is worth more but maybe not a lot more given how many of those are out there.
