I actually built a multivariate statistical model to measure the effects of a player's RC being a multi player card, which also measured the effects of their 2nd year card being their first solo card (and not, for those with solo RCs), and the effects of having the rookie cup on the card. The data I collected took all HOFers first 3 years of Topps cards (excluding 52 & 53) and their relative prices in similar grade/value ranges.
I'd have to dig to find it, but I seem to recall that having a multi player RC made it worth something like 30% less on average than it would have been were it to be a solo RC. And that having a 2nd year card with a rookie cup or trophy being a player's first solo card made it worth something like 20% more than it would have otherwise been were that not the case.
