I think it's even worse than a coin flip. At least with a coin there's a reasonable assumption that the odds are 50% both ways. Flipping the Duke/Mercer coin, though, you have have a maybe 95% of landing on Duke, which causes significantly more than 95% of people to put their money down on that, whereas with a normal unweighted coin you'd expect ~50% of people to bet on each side.
